For problem statement at 0-999/100-199/190-199/195/problemA.txt this is a correct solution, but verifier at 0-999/100-199/190-199/195/verifierA.go ends with All tests passed can you fix the verifier? ```go
package main

import "fmt"

func main() {
	var a, b, c int
	fmt.Scan(&a, &b, &c)
	
	// We need to find minimum integer t such that:
	// b * (t + c) >= a * c
	// b * t >= c * (a - b)
	// t >= c * (a - b) / b
	
	numerator := c * (a - b)
	// Ceiling division: (numerator + denominator - 1) / denominator
	ans := (numerator + b - 1) / b
	
	fmt.Println(ans)
}
```
