For problem statement at 1000-1999/1600-1699/1670-1679/1674/problemF.txt this is a correct solution, but verifier at 1000-1999/1600-1699/1670-1679/1674/verifierF.go ends with All tests passed. can you fix the verifier? ```go
package main

import (
	"bufio"
	"fmt"
	"os"
	"strconv"
	"strings"
)

type Fenwick struct {
	tree []int64

func NewFenwick(size int) *Fenwick {
	return &Fenwick{make([]int64, size+1)}
}

func (f *Fenwick) Update(idx int, delta int64) {
	for idx < len(f.tree) {
		f.tree[idx] += delta
		idx += idx & -idx
	}
}

func (f *Fenwick) Query(idx int) int64 {
	var sum int64
	for idx > 0 {
		sum += f.tree[idx]
		idx -= idx & -idx
	}
	return sum
}
