Remove whitespace at end of sentence

问题

这里是一些背景信息。

用户输入 test hello world (包括空白空格)

我需要将这个输入改为 test hello world

这是一些代码,如果我输入带有空格的前面的字符串,它只会删除一个空格,而在 trimsuffix 中添加多个空格将创建单个用例,例如只有 10 个空格。

package main

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

func main() {
	scanner := bufio.NewScanner(os.Stdin)
	scanner.Scan()
	text := scanner.Text() 
	text = strings.TrimSuffix(text, " ")
	fmt.Printf("%s", text)

}
英文:

Here's some context.

The user enters test hello world (including the empty whitespace)

I need this input to be changed into test hello world

Heres some code, if I enter the previous string with the whitespace, it only removes 1 space and adding more than one to the trimsuffix will create singular use cases such as only 10 spaces.

package main

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

func main() {
	scanner := bufio.NewScanner(os.Stdin)
	scanner.Scan()
	text := scanner.Text() 
	text = strings.TrimSuffix(text, " ")
	fmt.Printf("%s", text)

}

**得分**: 2

使用`text = strings.Trim(text, " ")`来去除两侧的空格

如果你只需要去除末尾的空格那么使用`text = strings.TrimRight(text, " ")`

Use `text = strings.Trim(text, &quot; &quot;)` to remove spaces on both sides.


If you only need at the end, then use `text = strings.TrimRight(text, &quot; &quot;)`
