Checksum Validation

Code

#include <stdio.h>

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