Go language provides inbuilt support for bits to implement bit counting and manipulation functions for the predeclared unsigned integer types with the help of bits package. This package provides Reverse8() function which is used to find the reversed order of the value of a. To access Reverse8() function you need to add a math/bits package in your program with the help of the import keyword.

Syntax:

 func Reverse8(a uint8) uint8

Parameters: This function takes one parameter of uint8 type, i.e., a.

Return Value: This function returns the value of a with its bits in reversed order.

Example 1:






// Golang program to illustrate bits.Reverse8() Function
package main
  
import (
    "fmt"
    "math/bits"
)
  
// Main function
func main() {
  
    // Using Reverse8() function
    a := bits.Reverse8(5)
    fmt.Printf("Reverse order of %d: %b", 5, a)
  
}

Output:

Reverse order of 5: 10100000

Example 2 :




// Golang program to illustrate bits.Reverse8() Function
package main
  
import (
    "fmt"
    "math/bits"
)
  
// Main function
func main() {
  
    // Using Reverse8() function
    a1 := bits.Reverse8(9)
    fmt.Printf("Reverse8(%08b) := %b\n", 9, a1)
  
    a2 := bits.Reverse8(13)
    fmt.Printf("Reverse8(%08b) := %b\n", 13, a2)
  
}

Output:

Reverse8(00001001) := 10010000
Reverse8(00001101) := 10110000
