# 35. Search Insert Position

###### Link : https://leetcode.com/problems/search-insert-position/description/

## 題目
在排序好的陣列中找到target，須維持O(log(n))
## 程式碼

```cpp=
class Solution {
public:
    int searchInsert(vector<int>& nums, int target) {
        int left = 0, right = nums.size() - 1;
        while(left <= right){
            int mid = (left + right) / 2;
            if(nums[mid] < target)
                left = mid + 1;
            else if(nums[mid] > target)
                right = mid - 1;
            else
                return mid;
        }
        return left;
    }
};
```
