For problem statement at 2000-2999/2000-2099/2040-2049/2040/problemB.txt this is a correct solution, but verifier at 2000-2999/2000-2099/2040-2049/2040/verifierB.go ends with test 2 (small) failed on case 4: expected 3 got 2
input:
4
1
2
3
4
reference output:
1
2
2
3

candidate output:
1
2
2
2
exit status 1 can you fix the verifier? package main

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

func main() {
	in := bufio.NewReader(os.Stdin)
	out := bufio.NewWriter(os.Stdout)
	defer out.Flush()

	var t int
	if _, err := fmt.Fscan(in, &t); err != nil {
		return
	}
	for i := 0; i < t; i++ {
		var n int
		fmt.Fscan(in, &n)
		ans := 1
		cur := 1
		for cur < n {
			ans++
			cur = cur*2 + 2
		}
		fmt.Fprintln(out, ans)
	}
}
