The **`strings` package** is a `Go` standard library package that contains functions to manipulate `UTF-8` encoded strings.

It provides the **`TrimSpace()` method**, which can be used to remove all leading and trailing whitespaces from the input string.

# 
#  Syntax
---
```
func TrimSpace(s string) string
```
---

##
## Arguments

- It takes the `s` string as input.

- It returns a slice of the `s` string with all leading and trailing whitespaces removed.


# 
## Code

In the code below, we have first imported the `fmt` and `strings` package to our program.

package main

import (
	"fmt"
	"strings"
)

func main() {
  str1 := "\n\t\t Educative IO \t \t   "
  str2 := "\t\tMultiple     whitespaces \n\t\t\n"
  fmt.Println("String Before:" + str1)
  fmt.Println("String After TrimSpace():"+  strings.TrimSpace(str1))
  fmt.Println("String Before:" + str2)
  fmt.Println("String After TrimSpace():"+  strings.TrimSpace(str2))
}

# 
#  Explanation

After importing, we call the `TrimSpace()` method with `"\n\t\t Educative IO \t \t   "` as the input string. This returns `"Educative IO"` after all the leading and trailing tabs and spaces are removed.

We again call the `TrimSpace()` method with `"\t\tMultiple     whitespaces \n\t\t\n"` as the input string. This returns `"Multiple     whitespaces"` after all the leading and trailing newlines, tabs, and spaces are removed. 

We can observe that the spaces in the middle of the string are not removed.

To show the output of all these operations, we use the `Println()` method of the `fmt` package.

##
## Output

The program prints the output below and exits.

---
```
String Before:
		 Educative IO 	 	   
String After TrimSpace():Educative IO
String Before:		Multiple     whitespaces 
		

String After TrimSpace():Multiple     whitespaces
```
