For problem statement at 1000-1999/1300-1399/1320-1329/1324/problemA.txt this is a correct solution, but verifier at 1000-1999/1300-1399/1320-1329/1324/verifierA.go ends with All tests passed can you fix the verifier? package main

import (
	"fmt"
)

func main() {
	var t int
	if _, err := fmt.Scan(&t); err != nil {
		return
	}
	for i := 0; i < t; i++ {
		var n int
		fmt.Scan(&n)
		var a int
		fmt.Scan(&a)
		rem := a % 2
		ok := true
		for j := 1; j < n; j++ {
			fmt.Scan(&a)
			if a%2 != rem {
				ok = false
			}
		}
		if ok {
			fmt.Println("YES")
		} else {
			fmt.Println("NO")
		}
	}
}
