201. Move Zeroes

EasyTwo Pointers

Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements. Note that you must do this in-place without making a copy of the array.

Examples

Input: [0,1,0,3,12]

Output: [1,3,12,0,0]

Explanation: Non-zero elements maintain their order, zeros move to end.

Constraints

  • 1 <= nums.length <= 10^4
  • -2^31 <= nums[i] <= 2^31 - 1
