Therefore, we can use binary search to find the largest difference that satisfies the condition. + +We define the left boundary of the binary search as $l = 0$ and the right boundary as $r = \textit{start}[-1] + d - \textit{start}[0]$. Each time, we take the middle value $mid = \left\lfloor \frac{l + r + 1}{2} \right\rfloor$ and check whether it satisfies the condition. + +We define a function $\text{check}(mi)$ to determine whether the condition is satisfied, implemented as follows: + +- We define a variable $\textit{last} = -\infty$, representing the last selected integer. +- We traverse the $\textit{start}$ array. If $\textit{last} + \textit{mi} > \textit{st} + d$, it means we cannot select the integer $\textit{st}$, and we return $\text{false}$.

    You are given an integer array nums of length n.

    + +

    Your goal is to start at index 0 and reach index n - 1. You can only jump to indices greater than your current index.

    + +

    The score for a jump from index i to index j is calculated as (j - i) * nums[i].

    + +

    Return the maximum possible total score by the time you reach the last index.

    + +

     

    +

    Example 1:

    + +
    +

    Input: nums = [1,3,1,5]

    + +

    Output: 7

    + +

    Explanation:

    + +

    First, jump to index 1 and then jump to the last index. The final score is 1 * 1 + 2 * 3 = 7.

    +
    + +

    Example 2:

    + +
    +

    Input: nums = [4,3,1,3,2]

    + +

    Output: 16

    + +

    Explanation:

    + +

    Jump directly to the last index. The final score is 4 * 4 = 16.

    +
    + +

     

    +

    Constraints:

    + +
      +
    • 1 <= nums.length <= 105
      • +
    • 1 <= nums[i] <= 105
      • +
    + + + +## Solutions + + + +### Solution 1: Greedy + +Suppose we jump from index $i$ to index $j$, then the score is $(j - i) \times \text{nums}[i]$. This is equivalent to taking $j - i$ steps, and each step earns a score of $\text{nums}[i]$. Then we continue to jump from $j$ to the next index $k$, and the score is $(k - j) \times \text{nums}[j]$, and so on. If $\text{nums}[i] \gt \text{nums}[j]$, then we should not jump from $i$ to $j$, because the score obtained this way is definitely less than the score obtained by jumping directly from $i$ to $k$. Therefore, each time we should jump to the next index with a value greater than the current index. + +We can maintain a variable $mx$ to represent the maximum value of $\text{nums}[i]$ encountered so far. Then we traverse the array from left to right until the second-to-last element, updating $mx$ each time and accumulating the score. + +After the traversal, the result is the maximum total score. + +The time complexity is $O(n)$, where $n$ is the length of the array $\text{nums}$. The space complexity is $O(1)$. + + + +#### Python3 + +```python +class Solution: + def findMaximumScore(self, nums: List[int]) -> int: + ans = mx = 0 + for x in nums[:-1]: + mx = max(mx, x) + ans += mx + return ans +``` + +#### Java + +```java +class Solution { + public long findMaximumScore(List nums) { + long ans = 0; + int mx = 0; + for (int i = 0; i + 1 < nums.size(); ++i) { + mx = Math.max(mx, nums.get(i)); + ans += mx; + } + return ans; + } +} +``` + +#### C++ + +```cpp +class Solution { +public: + long long findMaximumScore(vector& nums) { + long long ans = 0; + int mx = 0; + for (int i = 0; i + 1 < nums.size(); ++i) { + mx = max(mx, nums[i]); + ans += mx; + } + return ans; + } +}; +``` + +#### Go + +```go +func findMaximumScore(nums []int) (ans int64) { + mx := 0 + for _, x := range nums[:len(nums)-1] { + mx = max(mx, x) + ans += int64(mx) + } + return +} +``` + +#### TypeScript + +```ts +function findMaximumScore(nums: number[]): number { + let [ans, mx]: [number, number] = [0, 0]; + for (const x of nums.slice(0, -1)) { + mx = Math.max(mx, x); + ans += mx; + } + return ans; +} +``` + + + + + + diff --git a/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.cpp b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.cpp new file mode 100644 index 0000000000000..ccf8ddf036748 --- /dev/null +++ b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.cpp @@ -0,0 +1,12 @@ +class Solution { +public: + long long findMaximumScore(vector& nums) { + long long ans = 0; + int mx = 0; + for (int i = 0; i + 1 < nums.size(); ++i) { + mx = max(mx, nums[i]); + ans += mx; + } + return ans; + } +}; diff --git a/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.go b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.go new file mode 100644 index 0000000000000..3bd424cad51c0 --- /dev/null +++ b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.go @@ -0,0 +1,8 @@ +func findMaximumScore(nums []int) (ans int64) { + mx := 0 + for _, x := range nums[:len(nums)-1] { + mx = max(mx, x) + ans += int64(mx) + } + return +} diff --git a/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.java b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.java new file mode 100644 index 0000000000000..84ec81d88b56a --- /dev/null +++ b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.java @@ -0,0 +1,11 @@ +class Solution { + public long findMaximumScore(List nums) { + long ans = 0; + int mx = 0; + for (int i = 0; i + 1 < nums.size(); ++i) { + mx = Math.max(mx, nums.get(i)); + ans += mx; + } + return ans; + } +} diff --git a/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.py b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.py new file mode 100644 index 0000000000000..e9a53785baf0a --- /dev/null +++ b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.py @@ -0,0 +1,7 @@ +class Solution: + def findMaximumScore(self, nums: List[int]) -> int: + ans = mx = 0 + for x in nums[:-1]: + mx = max(mx, x) + ans += mx + return ans diff --git a/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.ts b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.ts new file mode 100644 index 0000000000000..74965ce06be97 --- /dev/null +++ b/solution/3200-3299/3282.Reach End of Array With Max Score/Solution.ts @@ -0,0 +1,8 @@ +function findMaximumScore(nums: number[]): number { + let [ans, mx]: [number, number] = [0, 0]; + for (const x of nums.slice(0, -1)) { + mx = Math.max(mx, x); + ans += mx; + } + return ans; +} diff --git a/solution/3200-3299/3283.Maximum Number of Moves to Kill All Pawns/README.md b/solution/3200-3299/3283.Maximum Number of Moves to Kill All Pawns/README.md new file mode 100644 index 0000000000000..84d6b4ea988b6 --- /dev/null +++ b/solution/3200-3299/3283.Maximum Number of Moves to Kill All Pawns/README.md @@ -0,0 +1,134 @@ +--- +comments: true +difficulty: 困难 +edit_url: https://github.com/doocs/leetcode/edit/main/solution/3200-3299/3283.Maximum%20Number%20of%20Moves%20to%20Kill%20All%20Pawns/README.md +--- + + + +# [3283. 吃掉所有兵需要的最多移动次数](https://leetcode.cn/problems/maximum-number-of-moves-to-kill-all-pawns) + +[English Version](/solution/3200-3299/3283.Maximum%20Number%20of%20Moves%20to%20Kill%20All%20Pawns/README_EN.md) + +## 题目描述 + + + +

    给你一个 50 x 50 的国际象棋棋盘，棋盘上有 一个 马和一些兵。给你两个整数 kx 和 ky ，其中 (kx, ky) 表示马所在的位置，同时还有一个二维数组 positions ，其中 positions[i] = [xi, yi] 表示第 i 个兵在棋盘上的位置。

    + +

    Alice 和 Bob 玩一个回合制游戏，Alice 先手。玩家的一次操作中，可以执行以下操作：

    + +
      +
    • 玩家选择一个仍然在棋盘上的兵，然后移动马，通过 最少 的 步数 吃掉这个兵。注意 ，玩家可以选择 任意 一个兵，不一定 要选择从马的位置出发 最少 移动步数的兵。
      • +
    • 在马吃兵的过程中，马 可能 会经过一些其他兵的位置，但这些兵 不会 被吃掉。只有 选中的兵在这个回合中被吃掉。
      • +
    + +

    Alice 的目标是 最大化 两名玩家的 总 移动次数，直到棋盘上不再存在兵，而 Bob 的目标是 最小化 总移动次数。

    + +

    假设两名玩家都采用 最优 策略，请你返回 Alice 可以达到的 最大 总移动次数。

    + +

    在一次 移动 中，如下图所示，马有 8 个可以移动到的位置，每个移动位置都是沿着坐标轴的一个方向前进 2 格，然后沿着垂直的方向前进 1 格。

    There is a 50 x 50 chessboard with one knight and some pawns on it. You are given two integers kx and ky where (kx, ky) denotes the position of the knight, and a 2D array positions where positions[i] = [xi, yi] denotes the position of the pawns on the chessboard.

    + +

    Alice and Bob play a turn-based game, where Alice goes first. In each player's turn:

    + +
      +
    • The player selects a pawn that still exists on the board and captures it with the knight in the fewest possible moves. Note that the player can select any pawn, it might not be one that can be captured in the least number of moves.
      • +
    • In the process of capturing the selected pawn, the knight may pass other pawns without capturing them. Only the selected pawn can be captured in this turn.
      • +
    + +

    Alice is trying to maximize the sum of the number of moves made by both players until there are no more pawns on the board, whereas Bob tries to minimize them.

    + +

    Return the maximum total number of moves made during the game that Alice can achieve, assuming both players play optimally.

    + +

    Note that in one move, a chess knight has eight possible positions it can move to, as illustrated below. Each move is two cells in a cardinal direction, then one cell in an orthogonal direction.

    + +

    + +

     

    +

    Example 1:

    + +
    +

    Input: kx = 1, ky = 1, positions = [[0,0]]

    + +

    Output: 4

    + +

    Explanation:

    + +

    + +

    The knight takes 4 moves to reach the pawn at (0, 0).

    +
    + +

    Example 2:

    + +
    +

    Input: kx = 0, ky = 2, positions = [[1,1],[2,2],[3,3]]

    + +

    Output: 8

    + +

    Explanation:

    + +

    + +
      +
    • Alice picks the pawn at (2, 2) and captures it in two moves: (0, 2) -> (1, 4) -> (2, 2).
      • +
    • Bob picks the pawn at (3, 3) and captures it in two moves: (2, 2) -> (4, 1) -> (3, 3).
      • +
    • Alice picks the pawn at (1, 1) and captures it in four moves: (3, 3) -> (4, 1) -> (2, 2) -> (0, 3) -> (1, 1).
      • +
    +
    + +

    Example 3:

    + +
    +

    Input: kx = 0, ky = 0, positions = [[1,2],[2,4]]

    + +

    Output: 3

    + +

    Explanation:

    + +
      +
    • Alice picks the pawn at (2, 4) and captures it in two moves: (0, 0) -> (1, 2) -> (2, 4). Note that the pawn at (1, 2) is not captured.
      • +
    • Bob picks the pawn at (1, 2) and captures it in one move: (2, 4) -> (1, 2).
      • +
    +
    + +

     

    +

    Constraints:

    + +
      +
    • 0 <= kx, ky <= 49
      • +
    • 1 <= positions.length <= 15
      • +
    • positions[i].length == 2
      • +
    • 0 <= positions[i][0], positions[i][1] <= 49
      • +
    • All positions[i] are unique.
      • +
    • The input is generated such that positions[i] != [kx, ky] for all 0 <= i < positions.length.
