Golang Program to count the number of flips to convert a given integer to another.

Go ProgrammingServer Side ProgrammingProgramming

Examples

Consider two numbers m = 65 => 01000001 and n = 80 => 01010000

Number of bits flipped is 2.

Approach to solve this problem

Step 1 − Convert both numbers into bits.

Step 2 − Count number of bits are flipped.

Example

 Live Demo

package main
import (
   "fmt"
   "strconv"
)
func FindBits(x, y int) int{
   n := x ^ y
   count := 0
   for ;n!=0; count++{
      n = n & (n-1)
   }
   return count
}
func main(){
   x := 65
   y := 80
   fmt.Printf("Binary of %d is: %s.\n", x, strconv.FormatInt(int64(x), 2))
   fmt.Printf("Binary of %d is: %s.\n", y, strconv.FormatInt(int64(y), 2))
   fmt.Printf("The number of bits flipped is %d\n", FindBits(x, y))
}

Output

Binary of 65 is: 1000001.
Binary of 80 is: 1010000.
The number of bits flipped is 2
