For problem statement at 0-999/900-999/920-929/928/problemA.txt this is a correct solution, but verifier at 0-999/900-999/920-929/928/verifierA.go ends with All tests passed can you fix the verifier? package main

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

	b := []byte(s)
	for i := 0; i < len(b); i++ {
		c := b[i]
		if c >= 'A' && c <= 'Z' {
			c = c + 'a' - 'A'
		}
		switch c {
		case 'o', '0':
			b[i] = '0'
		case '1', 'l', 'i':
			b[i] = '1'
		default:
			b[i] = c
		}
	}
	return string(b)
}
