Sum Input Values and Determine Difficulty

This C program reads a number 'n' from the user, then reads 'n' integers, summing them up. If the total sum is not zero, it outputs 'HARD'; otherwise, it outputs 'EASY'. This snippet is useful for understanding basic input/output operations and conditionals in C.

#include<stdio.h>

int main() 
{
    int n, i, a;
    int total = 0;

    scanf("%d", &n);
    for(i = 0; i < n; i++) 
    {
        scanf("%d", &a);
        total += a;
    }
    if(total != 0) 
    {
        printf("HARD\n");
    } 
    else 
    {
        printf("EASY\n");
    }
    return 0;
}
