Description: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.
implementation(C++):
class Solution {
public:
vector<int> sortedSquares(vector<int>& A) {
for(int i=0;i<A.size();i++)
{A[i]=abs(A[i]);}
sort(A.begin(),A.end());
for(int i=0;i<A.size();i++)
{A[i]=A[i]*A[i];}
return A;
}
};

博客围绕Leetcode题目展开,给定一个非递减排序的整数数组A,要求返回每个数字平方后仍按非递减顺序排序的数组。给出两个示例输入输出,并说明了数组长度和元素范围,还给出了C++实现及参考网址。
