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!
