Checksum Validation

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    int test = 0; 
    // int size = sizeof(mem)/sizeof(mem[0]);

    for (int i = 0 ; i < n-1 ; i++){
        test ^= mem[i];
    }

    if (test == mem[n-1]) {return 1;}
    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;
}
