#include <stdio.h>
void main()
{
    int x, a, b, c, f, z,sum;
    printf ("input x");
    scanf ("%d", &x);
    a = x / 1000;
    f = x % 10;
    b = (x - a * 1000) / 100;
    c = (x - a * 1000 - b * 100) / 10;
    z = f * 1000 + c * 100 + b * 10 + a * 1;
    sum = a + b + c + f;
    printf("a=%d, b=%d, c=%d, f=%d, z=%d, sum=%d",a, b, c, f, z,sum);
