Problem

Given an array of random positive numbers, move all the zeroes to the left of the array.

Conditions

  1. has to be done in place ( space-constrained, ie. cannot allocate a new array)
  2. the order of non-zero elements on the right do not matter

Example

Input : arr[] = {0, 1, 2, 5, 0, 3, 0, 3};
Output : arr[] = {0, 0, 0, 2, 1, 3, 3, 5};

Solution

Python

Golang

Takeaways

I hope this blog post helps someone struggling to understand on how to solve this problem. Stay tuned to the next post! Peace ✌️
