Leetcode - Sort Array By Parity Solution
Given an array
A of non-negative integers, return an array consisting of all the even elements of
A, followed by all the odd elements of
You may return any answer array that satisfies this condition.
Input: [3,1,2,4] Output: [2,4,3,1] The outputs [4,2,3,1], [2,4,1,3], and [4,2,1,3] would also be accepted.
1 <= A.length <= 5000
0 <= A[i] <= 5000
Solution in Python
from collections import deque class Solution: def sortArrayByParity(self, A: List[int]) -> List[int]: arr = deque() for i in A: if i%2: arr.append(i) else: arr.appendleft(i) return arr
