For problem statement at 0-999/800-899/860-869/866/problemC.txt this is a correct solution, but verifier at 0-999/800-899/860-869/866/verifierC.go ends with All 100 tests passed can you fix the verifier? package main

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

func main() {
	in := bufio.NewReader(os.Stdin)
	var s string
	if _, err := fmt.Fscan(in, &s); err != nil {
		return
	}
	r := []rune(s)
	i, j := 0, len(r)-1
	ans := "YES"
	for i < j {
		if r[i] != r[j] {
			ans = "NO"
			break
		}
		i++
		j--
	}
	fmt.Println(ans)
}
