Checksum Validation

Code

#include <stdio.h>

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