Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    if(n == 0 || mem == NULL)
    {
        return 0; 
    }

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

    if(checkSum == 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;
}
