Checksum Validation

Code

#include <stdio.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    int temp, checksum;
    for(int i = 0;i<n;i++){
        if(i==(n-1)) checksum =mem[i]&0xFF;
        else
        temp ^= mem[i] &0xFF;
    }
     if(temp==checksum)
     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;
}
