For problem statement at 1000-1999/1500-1599/1530-1539/1530/problemA.txt this is a correct solution, but verifier at 1000-1999/1500-1599/1530-1539/1530/verifierA.go ends with Accepted can you fix the verifier? ```go
package main

import "fmt"

func main() {
	var t int
	fmt.Scan(&t)
	for i := 0; i < t; i++ {
		var n int
		fmt.Scan(&n)
		maxDigit := 0
		for n > 0 {
			digit := n % 10
			if digit > maxDigit {
				maxDigit = digit
			}
			n /= 10
		}
		fmt.Println(maxDigit)
	}
}
```
