Updated Jan 31, 2026
Problem
Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements.
Return the array after moving zeros.
Constraints
1 <= nums.length <= 10^4
-2^31 <= nums[i] <= 2^31 - 1
Examples
Example 1
Input:
nums = [0, 1, 0, 3, 12]
Output:
[1, 3, 12, 0, 0]
Example 2
Input:
nums = [0]
Output:
[0]
Example 3
Input:
nums = [1, 0, 1]
Output:
[1, 1, 0]
Function Signature
def moveZeroes(self, nums: list[int]) -> list[int]
How to Submit
Implement a Solution class with a moveZeroes method.
Your method will be called with the input parameters and should return the answer.
