+# [41. First Missing Positive](https://leetcode.com/problems/first-missing-positive/description/)
+
+## 题目
+
+Given an unsorted integer array, find the smallest missing positive integer.
+
+Example 1:
+
+Input: [1,2,0]
+Output: 3
+Example 2:
+
+Input: [3,4,-1,1]
+Output: 2
+Example 3:
+
+Input: [7,8,9,11,12]
+Output: 1
+Note:
+
+Your algorithm should run in O(n) time and uses constant extra space.
