For problem statement at 0-999/100-199/180-189/189/problemB.txt this is a correct solution, but verifier at 0-999/100-199/180-189/189/verifierB.go ends with all tests passed can you fix the verifier? package main

import "fmt"

func main() {
	var w, h int64
	fmt.Scan(&w, &h)
	ans := (w / 2) * ((w + 1) / 2) * (h / 2) * ((h + 1) / 2)
	fmt.Println(ans)
}
