Checksum Validation

Code

#include <stdio.h>
#include <stdint.h>

int validate_checksum(int *mem, int n) {
    int result = mem[0];
    // Write your XOR scan logic here
    for (uint8_t ArrIndex = 1;ArrIndex < (n-1);ArrIndex++)
       result ^= (mem[ArrIndex]) ;

    if((result) == mem[n-1])
      return 1;
    else if((result & 0x0001) == mem[n-1])
      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;
}
