How to Seperate Non-Zero elements & Zero's

Given an array of integers, Move all non-zero elements to the left of all zero elements.


Implementation:

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
#define MAX 1000
int main()
{
    int t,size,arr[MAX],i,j,brr[MAX];
    
    /* Get the number of test cases */
    scanf("%d",&t);
    
    while(t--)
    {
     /* Get the size of the array */
        scanf("%d",&size);
        
        /* Get the elements of the array */
        for(i=0;i<size;i++)
         scanf("%d",&arr[i]);
        
        for(i=0,j=0;i<size;i++)
        {
            if(arr[i]!=0)
            {
                brr[j]=arr[i];
                j++;
            }
            else
                continue;
        }
        
        for(i=j;i<size;i++)
         brr[i]=0;
         
        for(i=0;i<size;i++)
        {
            printf("%d",brr[i]);
            if(i==(size-1))
            {
                printf("\n");
            }
            else
               {
                   printf(" ");
               }
        }
    }
    return 0;
}
