How to reverse a byte slice in Go using the bytes package?

To reverse a byte slice in Go using the bytes package, you can use the Reverse function along with the bytes package. Here's an example:

package main

import (
	"bytes"
	"fmt"
)

func main() {
	byteSlice := []byte{'a', 'b', 'c', 'd', 'e'}
	reversedSlice := reverse(byteSlice)
	fmt.Println(string(reversedSlice)) // Output: edcba
}

func reverse(input []byte) []byte {
	result := make([]byte, len(input))
	copy(result, input)

	bytes.Reverse(result)
	return result
}

In this example, we define a reverse function that takes in a byte slice as input and returns a reversed byte slice.

To reverse the byte slice, we first create a new byte slice called result with the same length as the input slice and copy the input slice values into it.

Then, we use the bytes.Reverse function to reverse the byte slice in-place.

Finally, we return the reversed byte slice.
