+## [猜数字大小](https://leetcode-cn.com/problems/guess-number-higher-or-lower/)
+
+猜数字游戏的规则如下：
+
+*   每轮游戏，我都会从 **1** 到 _**n**_ 随机选择一个数字。 请你猜选出的是哪个数字。
+*   如果你猜错了，我会告诉你，你猜测的数字比我选出的数字是大了还是小了。
+
+你可以通过调用一个预先定义好的接口 `int guess(int num)` 来获取猜测结果，返回值一共有 3 种可能的情况（`-1`，`1` 或 `0`）：
+
+*   -1：我选出的数字比你猜的数字小 `pick 
+ num`
+*   0：我选出的数字和你猜的数字一样。恭喜！你猜对了！`pick == num`
+
+ 
+
+**示例 1：**
+
+`
+**输入：**n = 10, pick = 6
+**输出：**6
+`
+
+**示例 2：**
+
+`
+**输入：**n = 1, pick = 1
+**输出：**1
+`
+
+**示例 3：**
+
+`
+**输入：**n = 2, pick = 1
+**输出：**1
+`
+
+**示例 4：**
+
+`
+**输入：**n = 2, pick = 2
+**输出：**2
+`
+
+ 
+
+**提示：**
+
+*   `1 
+31
+ - 1`
+*   `1 <= pick <= n`
