How to create a compressed stream using the compress/flate package in Go?

To create a compressed stream using the compress/flate package in Go, you can follow these steps:

Import the necessary packages:

import (
	"compress/flate"
	"io"
	"os"
)

Create a file to write the compressed data:

file, err := os.Create("compressed.bin")
if err != nil {
    panic(err)
}
defer file.Close()

Create a flWriter using flate.NewWriter():

flWriter, err := flate.NewWriter(file, flate.DefaultCompression)
if err != nil {
    panic(err)
}
defer flWriter.Close()

Write the data you want to compress using the Write() method:

data := []byte("This is the data to compress")
_, err = flWriter.Write(data)
if err != nil {
    panic(err)
}

Flush the writer to make sure all the data is written:

err = flWriter.Flush()
if err != nil {
    panic(err)
}

That's it! You have successfully created a compressed stream using the compress/flate package in Go. The compressed data will be written to the "compressed.bin" file.
