For problem statement at 1000-1999/1100-1199/1110-1119/1113/problemA.txt this is a correct solution, but verifier at 1000-1999/1100-1199/1110-1119/1113/verifierA.go ends with case 2 failed
input:
55 6
expected:
1230
got:
102

exit status 1 can you fix the verifier? ```go
package main

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

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

	if v >= n-1 {
		fmt.Print(n - 1)
		return
	}

	cost := v
	fuel := v
	for city := 2; city <= n-1; city++ {
		fuel--
		remainingDist := n - city
		if remainingDist > v {
			target := remainingDist
			if fuel < target {
				buy := target - fuel
				cost += buy * city
				fuel += buy
			}
		}
	}
	fmt.Print(cost)
}
```
