For problem statement at 0-999/100-199/130-139/130/problemB.txt this is a correct solution, but verifier at 0-999/100-199/130-139/130/verifierB.go ends with All tests passed can you fix the verifier? ```go
package main

import "fmt"

func main() {
    var s string
    fmt.Scan(&s)
    bytes := []byte(s)
    for i, j := 0, len(bytes)-1; i < j; i, j = i+1, j-1 {
        bytes[i], bytes[j] = bytes[j], bytes[i]
    }
    fmt.Println(string(bytes))
}
```
