Checksum Validation

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    int *end = mem + n;
    int result = 0;

    for(mem; mem < (end - 1); mem++){
        result ^= *mem;
    }

    if(result == *(end - 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;
}
