### 方法一
83+
### 方法一：模拟
84+
85+
我们用一个长度为 $n$ 的布尔数组 $\textit{vis}$ 记录已经被使用的篮子，用一个答案变量 $\textit{ans}$ 记录所有未被放置的水果，初始时 $\textit{ans} = n$。
86+
87+
接下来，我们遍历每一种水果 $x$，对于当前水果，我们遍历所有的篮子，找出第一个未被使用，且容量大于等于 $x$ 的篮子 $i$。如果找到了，那么答案 $\textit{ans}$ 减 $1$。
88+
89+
遍历结束后，返回答案即可。
90+
91+
时间复杂度 $O(n)$，空间复杂度 $O(n)$。其中 $n$ 是数组 $\textit{fruits}$ 的长度。

### Solution 1
81+
### Solution 1: Simulation
82+
83+
We use a boolean array $\textit{vis}$ of length $n$ to record the baskets that have already been used, and a variable $\textit{ans}$ to record the number of fruits that have not been placed, initially $\textit{ans} = n$.
84+
85+
Next, we traverse each fruit $x$. For the current fruit, we traverse all the baskets to find the first unused basket $i$ with a capacity greater than or equal to $x$. If found, we decrement $\textit{ans}$ by $1$.
86+
87+
After traversing, we return the answer.
88+
89+
The time complexity is $O(n)$, and the space complexity is $O(n)$. Here, $n$ is the length of the array $\textit{fruits}$.
