+
+力扣题目链接：[https://leetcode.cn/problems/distribute-candies/](https://leetcode.cn/problems/distribute-candies/)
+
+<p>Alice 有 <code>n</code> 枚糖，其中第 <code>i</code> 枚糖的类型为 <code>candyType[i]</code> 。Alice 注意到她的体重正在增长，所以前去拜访了一位医生。</p>
+
+<p>医生建议 Alice 要少摄入糖分，只吃掉她所有糖的 <code>n / 2</code> 即可（<code>n</code> 是一个偶数）。Alice 非常喜欢这些糖，她想要在遵循医生建议的情况下，尽可能吃到最多不同种类的糖。</p>
+
+<p>给你一个长度为 <code>n</code> 的整数数组 <code>candyType</code> ，返回： Alice <em>在仅吃掉 <code>n / 2</code> 枚糖的情况下，可以吃到糖的 <strong>最多</strong> 种类数</em>。</p>
+
+<p>&nbsp;</p>
+
+<p><strong>示例 1：</strong></p>
+
+<pre>
+<strong>输入：</strong>candyType = [1,1,2,2,3,3]
+<strong>输出：</strong>3
+<strong>解释：</strong>Alice 只能吃 6 / 2 = 3 枚糖，由于只有 3 种糖，她可以每种吃一枚。
+</pre>
+
+<p><strong>示例 2：</strong></p>
+
+<pre>
+<strong>输入：</strong>candyType = [1,1,2,3]
+<strong>输出：</strong>2
+<strong>解释：</strong>Alice 只能吃 4 / 2 = 2 枚糖，不管她选择吃的种类是 [1,2]、[1,3] 还是 [2,3]，她只能吃到两种不同类的糖。
+</pre>
+
+<p><strong>示例 3：</strong></p>
+
+<pre>
+<strong>输入：</strong>candyType = [6,6,6,6]
+<strong>输出：</strong>1
+<strong>解释：</strong>Alice 只能吃 4 / 2 = 2 枚糖，尽管她能吃 2 枚，但只能吃到 1 种糖。
+</pre>
+
+<p>&nbsp;</p>
+
+<p><strong>提示：</strong></p>
+
+<ul>
+	<li><code>n == candyType.length</code></li>
+	<li><code>2 &lt;= n &lt;= 10<sup>4</sup></code></li>
+	<li><code>n</code> 是一个偶数</li>
+	<li><code>-10<sup>5</sup> &lt;= candyType[i] &lt;= 10<sup>5</sup></code></li>
+</ul>
+
+
+    
+## 解题方法：比较
+
+限制Alice能吃到糖的种类的因素有两个：
+
+1. 糖本身的种类——无论Alice使用什么策略都无法突破糖原本种类数的限制；
+2. 糖的总个数——医生让她最多吃一半数量的糖。
+
+因此最终答案为$\min(type, \frac{size}2)$
+
++ 时间复杂度$O(size)$
++ 空间复杂度$O(size)$
+
+### AC代码
+
+#### C++
+
+```cpp
+class Solution {
+public:
+    int distributeCandies(vector<int>& candyType) {
+        set<int> se(candyType.begin(), candyType.end());
+        return min(se.size(), candyType.size() / 2);
+    }
+};
+```
+
+#### Go
+
+```go
+package main
+
+func min(a int, b int) int {
+    if a <= b {
+        return a
+    }
+    return b
+}
+
+func distributeCandies(candyType []int) int {
+    se := make(map[int]int)
+    for _, t := range candyType {
+        se[t] = 0
+    }
+    return min(len(se), len(candyType) / 2)
+}
+```
+
+#### Java
+
+```java
+// import java.util.HashSet;
+// import java.util.Set;
+
+class Solution {
+    public int distributeCandies(int[] candyType) {
+        Set<Integer> se = new HashSet<>();
+        for (int t : candyType) {
+            se.add(t);
+        }
+        return Math.min(se.size(), candyType.length / 2);
+    }
+}
+```
+
+#### Python
+
+```python
+# from typing import List
+
+class Solution:
+    def distributeCandies(self, candyType: List[int]) -> int:
+        return min(len(set(candyType)), len(candyType) // 2)
