Problem: Move Zeroes

med
30 min
Explore how to efficiently move all zeroes to the end of an integer array in-place using the two pointers pattern. Understand the problem constraints, preserve the order of non-zero elements, and implement an optimized solution without extra space.

Statement

Given an integer array, nums, rearrange the elements such that all 0s0's are moved to the end of the array, while the relative order of all non-zero elements is preserved.

Note: The operation must be performed in-place, without creating a copy of the array.

Constraints:

  • 11 \leq nums.length 104\leq 10^4

  • 231-2^{31} \leq nums[i] 2311\leq 2^{31} - 1
