For problem statement at 0-999/600-699/660-669/661/problemA.txt this is a correct solution, but verifier at 0-999/600-699/660-669/661/verifierA.go ends with All 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 n int64
		fmt.Fscan(reader, &n)
		fmt.Fprintln(writer, (n*(n+1))/2+1)
	}
}
