Golang Program to Determine Recursively Whether a Given Number is Even or Odd

Steps

• Take a number from the user and store it in a variable.
• Pass the number as an argument to a recursive function.
• Define the base condition as the number to be lesser than 2.
• Otherwise, call the function recursively with the number minus 2.
• Then, return the result and check if the number is even or odd.
• Print the final result.

Example

 Live Demo

package main
import (
   "fmt"
)
func check(n int) bool{
   if n < 2 {
      return n % 2 == 0
   }
   return check(n - 2)
}
func main(){
   var number int
   fmt.Print("Enter a number:")
   fmt.Scanf("%d", &number)
   check(number)
   if check(number)==true {
      fmt.Println("Number is even!")
   }else{
      fmt.Println("Number is odd!")
   }
}

Output

Enter a number:8
Number is even!
