For problem statement at 0-999/400-499/490-499/492/problemA.txt this is a correct solution, but verifier at 0-999/400-499/490-499/492/verifierA.go ends with All tests passed can you fix the verifier? ```go
package main

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

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

	sum := 0
	h := 0
	for i := 1; ; i++ {
		level := i * (i + 1) / 2
		if sum+level > n {
			break
		}
		sum += level
		h++
	}
	fmt.Print(h)
}
```
