Instructions

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

If the int is 0 or a negative number return the original string.

Expected function

func SaveAndMiss(arg string, num int) string {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
)

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

And its output:

$ go run . | cat -e
123789$
abcghimnostuz$
$
hello you all ! $
what is your name?$
go Exercise Save and Miss$
