Given an integer array nums, move all the even integers at the beginning of the array followed by all the odd integers.

Return any array that satisfies this condition.

 

Example 1:

Input: nums = [3,1,2,4]
Output: [2,4,3,1]
Explanation: The outputs [4,2,3,1], [2,4,1,3], and [4,2,1,3] would also be accepted.

Example 2:

Input: nums = [0]
Output: [0]

 

Constraints:

  • 1 <= nums.length <= 5000
  • 0 <= nums[i] <= 5000




 class Solution:
    def sortArrayByParity(self, nums: List[int]) -> List[int]:

        odd = []
        even = []

        for num in nums:
            if num % 2 == 0:
                even.append(num)
            else:
                odd.append(num)

        return even+odd
