Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    if(mem == NULL || n<2){
        return 0;
    }
    int calculated_checksum=0;
    for (int i=0; i<n-1; i++){
        calculated_checksum ^= mem[i];

    }
    int stored_checksum =mem[n-1];
    return (calculated_checksum==stored_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;
}
