printandmiss

Instructions

Write a function called PrintAndMiss() that takes a string and an int as an argument. The function should move through the string in sets determined by the int, printing the first set, omitting the second, printing the third, and so on, in a 'print' and 'miss' fashion until the end of the string is reached. Return a string containing the printed characters.

• If the string is empty or the int is negative return Invalid Output followed by newline \n.
• If the int is 0 return the string followed by a newline \n.

Expected function

func PrintAndMiss(arg string, num int) string {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Print(piscine.PrintAndMiss("123456789", 3))
	fmt.Print(piscine.PrintAndMiss("abcdefghijklmnopqrstuvwyz", 3))
	fmt.Print(piscine.PrintAndMiss("", 3))
	fmt.Print(piscine.PrintAndMiss("hello you all ! ", 0))
	fmt.Print(piscine.PrintAndMiss("what is your name?", 0))
	fmt.Print(piscine.PrintAndMiss("go Exercise Print and Miss", -5))
}

And its output:

$ go run . | cat -e
123789$
abcghimnostuz$
Invalid Output$
hello you all ! $
what is your name?$
Invalid Output$
