Print Numbers in a Range without Using Loops in Go

Steps

• Define a recursive function.
• Define a base case for that function that the number should be greater than zero.
• If the number is greater than 0, call the function again with the argument as the number minus 1.
• Print the number.

Example

 Live Demo

package main
import (
   "fmt"
)
func printNo(number int){
   if number >= 1{
      printNo(number-1)
      fmt.Println(number)
   }
}
func main(){
   var upper int
   fmt.Print("Enter the upper limit: ")
   fmt.Scanf("%d", &upper)
   printNo(upper)
}

Output

Enter the upper limit: 5
