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