一、题目描述
Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order.
You may assume no duplicates in the array.
Here are few examples.
[1,3,5,6]
, 5 → 2
[1,3,5,6]
, 2 → 1
[1,3,5,6]
, 7 → 4
[1,3,5,6]
, 0 → 0
思路:遍历一次数组,遇到大于等于target 就返回当前位置。否则返回容器大小。

class Solution {
public:
int searchInsert(vector<int>& nums, int target) {
int len=nums.size();
for(int i=0; i<len; i++){
if(nums[i]>=target)
return i;
}
return len;
}
};
