Checksum Validation

Code

#include <stdio.h>

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