# Golang Program to find the parity of a given number.

Definition − Parity refers to the count of 1s. If count of 1s is even, then it’s even parity; and if the count of 1s is odd, then the parity is Odd.

## Examples

Consider n = 20(00010100)

Parity of the given number 20 is even.

Approach to solve this problem

Step 1 − Define a method, where n and is an argument, return type is int.

Step 2 − Calculate the count of 1s in the given number’s bit.

## Example

Live Demo

package main
import (
"fmt"
"strconv"
)
func FindParity(n int) bool {
parity := false
for n != 0 {
if n & 1 != 0{
parity = !parity
}
n = n >> 1
}
return parity
}
func main(){
n := 20
fmt.Printf("Binary of %d is: %s.\n", n, strconv.FormatInt(int64(n), 2))
if FindParity(n){
fmt.Printf("Parity of the %d is Odd.\n", n)
} else {
fmt.Printf("Parity of the %d is Even.\n", n)
}
}

## Output

Binary of 20 is: 10100.
Parity of the 20 is Even.
