Move all zeroes to end of array | Set | function to move all zeroes at the end of array ; Count of non - zero elements ; Traverse the array . If arr [ i ] is non - zero , then swap the element at index ' count ' with the element at index 'i   ; function to print the array elements ; Driver program to test above
