问题描述

正在自学go语言，命令行执行以下程序，进入等待输入状态，请问如何处理？

package main

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

func main() {
counts := make(map[string]int)
input := bufio.NewScanner(os.Stdin)
for input.Scan() {
counts[input.Text()]++
}
// NOTE: ignoring potential errors from input.Err()
for line n := range counts {
if n > 1 {
fmt.Printf(""%dt%sn"" n line)
}
}
}
