For problem statement at 1000-1999/1400-1499/1460-1469/1463/problemB.txt this is a correct solution, but verifier at 1000-1999/1400-1499/1460-1469/1463/verifierB.go ends with All 100 tests passed can you fix the verifier? package main

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

func main() {
	in := bufio.NewReaderSize(os.Stdin, 1<<20)
	out := bufio.NewWriterSize(os.Stdout, 1<<20)
	defer out.Flush()

	var t int
	fmt.Fscan(in, &t)
	for ; t > 0; t-- {
		var n int
		fmt.Fscan(in, &n)
		for i := 0; i < n; i++ {
			var a int64
			fmt.Fscan(in, &a)
			var b int64 = 1
			for (b << 1) <= a {
				b <<= 1
			}
			if i > 0 {
				fmt.Fprint(out, " ")
			}
			fmt.Fprint(out, b)
		}
		fmt.Fprintln(out)
	}
}
