【leetcode】977. Squares of a Sorted Array

题目如下:

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.

解题思路:在leetcode,还有比这更简单的题目吗?

闲聊:最近在出差,都没有时间刷题。今天刷个容易的题保持手感吧。

代码如下:

class Solution(object):
    def sortedSquares(self, A):
        """
        :type A: List[int]
        :rtype: List[int]
        """
        def f(x):
            return x*x
        return sorted(map(f,A))
