#include<stdio.h>

int main(){

    int a, b, c;
    printf("Masukan waktu saat ini : ");
    scanf("%d",&a);
    printf("Masukan sisa waktu sampai kontes di mulai : ");
    scanf("%d",&b);
    if(a+b>=24){
        c=(a+b)-(((a+b)/24)*24);
        printf("\nKontes akan dimulai ");
        printf("%d",c);
    }
    else {
        c=a+b;
        printf("\nKontes akan dimulai ");
        printf("%d",c);

    printf("\n\n\t\t\tTerimaKasih\n\n\n");
    }
