Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    int *p = mem;
    int xor_rsl =0;
    for(int i=0l; i<n-1; i++){
        xor_rsl ^= *p;
        p++;
    }

    int checksum = *p;
    return xor_rsl == checksum ? 1:0;
}

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;
}
