Push all the zero’s of a given array to the end of the array.

Question

Given an array of random numbers, Push all the zero’s of a given array to the end of the array.

Answer 1

void PushZero(int *array, int n)
{
    int no = 0;  
    for (int i = 0; i < n; i++)
        if (array[i] != 0)
            array[no++] = array[i];

    while (no < n)
        array[no++] = 0;
}

Replace 0 with next number and Count no of 0.
Now assign zeros in last.

Answer 2

let I point first value and J point last value.

i++, j--
condition goes until hit i>=j

swap I and J, if I ==0
