    Using abs() from stdlib

    #include <stdio.h>
#include <stdlib.h>

void update(int *a,int *b) {
    // Complete this function
    int aTemp = *a;
    int bTemp = *b;
    *a = aTemp + bTemp;
    *b = abs(aTemp - bTemp);
}

int main() {
    int a, b;
    int *pa = &a, *pb = &b;
    
    scanf("%d %d", &a, &b);
    update(pa, pb);
    printf("%d\n%d", a, b);

    return 0;
}
