Move all zeroes to end of array in C++

Given array with multiple zeroes in it. We have to move all the zeroes in the array to the end. Let's see an example.

Input

arr = [4, 5, 0, 3, 2, 0, 0, 0, 5, 0, 1]

Output

4 5 3 2 5 1 0 0 0 0 0

Algorithm

• Initialise the array.

• Initialise an index to 0.

• Iterate over the given array.

  • If the current element is not zero, then update the value at the index with the current element.

  • Increment the index.

• Write a loop that iterates from the above index to n

  • Update all the elements to 0.

Implementation

Following is the implementation of the above algorithm in C++

#include 
using namespace std;
void moveZeroesToEnd(int arr[], int n) {
   int index = 0;
   for (int i = 0; i 
Output
If you run the above code, then you will get the following result.
4 5 3 2 5 1 0 0 0 0 0
