Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    if (n == 0) return 0;
    int result = mem[0]; // this is for initial value

    //XOR computation
    for (int x = 0; x < n - 1; x++)
    {
        //XOR first element and second element
        int checksum_val = mem[x+1];
        result ^= checksum_val;
    }
    if (result == 0) 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;
}
