Checksum Validation

Code

#include <stdio.h>
#include <stdint.h>

int validate_checksum(int *mem, int n) {
    // Write your XOR scan logic here
    uint8_t temp = 0;
    for ( uint8_t i = 0; i < n-1; i++)
    {
        temp ^= mem[i];
        //temp |= temp; //not necessary!
    }
    if (temp == mem[n-1])
    {
        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;
}
