Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {

    int suma = 0;
    for (int i=0 ; i<n-1 ; i++)
    {
        suma ^= mem[i];
    }
    if(suma == mem[n-1])
    {
        return 1;
    } else {
        return 0;
    }

}

int main() {
    int n, arr[100];
    scanf("%d", &n);
    
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int result = validate_checksum(arr, n);
    printf("%d", result);

    return 0;
}
