Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    int xorSum = 0;
    int outVal = 0;
    for (int i = 0;i < n-1; i++)
    {
        xorSum ^= mem[i];
    }

    if (mem[n-1] == xorSum)
    {
        outVal = 1;
    }

    return outVal;
}

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;
}
