For problem statement at 1000-1999/1900-1999/1960-1969/1969/problemB.txt this is a correct solution, but verifier at 1000-1999/1900-1999/1960-1969/1969/verifierB.go ends with All 99 tests passed can you fix the verifier? package main

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

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

	var t int
	fmt.Fscan(reader, &t)

	for i := 0; i < t; i++ {
		var s string
		fmt.Fscan(reader, &s)

		var ones int64 = 0
		var ans int64 = 0

		for _, c := range s {
			if c == '1' {
				ones++
			} else if ones > 0 {
				ans += ones + 1
			}
		}
		fmt.Fprintln(writer, ans)
	}
