For problem statement at 1000-1999/1000-1099/1070-1079/1076/problemA.txt this is a correct solution, but verifier at 1000-1999/1000-1099/1070-1079/1076/verifierA.go ends with All tests passed can you fix the verifier? package main

import (
	"bufio"
	"fmt"
	"os"
)

func main() {
	r := bufio.NewReader(os.Stdin)
	var n int
	var s string
	fmt.Fscan(r, &n, &s)

	for i := 0; i < n-1; i++ {
		if s[i] > s[i+1] {
			fmt.Println(s[:i] + s[i+1:])
			return
		}
	}
	if n > 0 {
		fmt.Println(s[:n-1])
	}
}
