doppelganger

WARNING! VERY IMPORTANT!

For this exercise a function will be tested with the exam own main. However the student still needs to submit a structured program:

This means that:

• The package needs to be named package main.
• The submitted code needs one declared function main(func main()) even if empty.
• The function main declared needs to also pass the Restrictions Checker(illegal functions tester). It is advised for the student to just empty the function main after its own testings are done.
• Every other rules are obviously the same than for a program.

Instructions

You are given 2 strings. Find out if first string contains second string. If it does, return index of the first string where second string occurs last time. If it does not contain, return "-1"

Expected function

package main

func DoppelGanger(big, little string) int {

}

package main

import (
	"fmt"
)

func main() {
	var result int

	result = DoppelGanger("aaaaaaa", "a")
	fmt.Println(result) // 6

	result = DoppelGanger("qwerty", "t")
	fmt.Println(result) // 4

	result = DoppelGanger("a", "b")
	fmt.Println(result) // -1
}
