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 <= A.length <= 10000
-10000 <= A[i] <= 10000
-
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;
}
};
