#Leetcode# 977. Squares of a Sorted Array

https://leetcode.com/problems/squares-of-a-sorted-array/

Given an array of integers A sorted in non-decreasing order, return an array of the squares of each number, also in sorted non-decreasing order.

Example 1:

Input: [-4,-1,0,3,10]
Output: [0,1,9,16,100]

Example 2:

Input: [-7,-3,2,3,11]
Output: [4,9,9,49,121]

Note:

1. 1 <= A.length <= 10000
2. -10000 <= A[i] <= 10000
3. A is sorted in non-decreasing order.

代码：

class Solution {
public:
    vector<int> sortedSquares(vector<int>& A) {
        vector<int> ans;
        int n = A.size();
        //sort(A.begin(), A.end());
        for(int i = 0; i < n; i ++) {
            ans.push_back(A[i] * A[i]);
        }
        sort(ans.begin(), ans.end());
        return ans;
    }
};
