Checksum Validation

Code

#include <stdio.h>

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


    }
    return checksum == * (mem + (n - 1)) ? 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;
}
