For problem statement at 1000-1999/1200-1299/1250-1259/1256/problemA.txt this is a correct solution, but verifier at 1000-1999/1200-1299/1250-1259/1256/verifierA.go ends with All tests passed can you fix the verifier? package main

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

func min(a, b int64) int64 {
	if a < b {
		return a
	}
	return b
}

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

	var q int
	if _, err := fmt.Fscan(in, &q); err != nil {
		return
	}
	for i := 0; i < q; i++ {
		var a, b, n, S int64
		fmt.Fscan(in, &a, &b, &n, &S)
		x := min(a, S/n)
		if S-x*n <= b {
			fmt.Fprintln(out, "YES")
		} else {
			fmt.Fprintln(out, "NO")
		}
	}
}
