DIRECTIONS : Complete the method below.

You will be writing only the go method.

The go method should:

Two words are sent in to the go method as word1 and letter1

You will RETURN an int containing the SUM of both locations for letter1 in word1

The answer will be printed in main so you do not need any System.out.println

Show your work is there if you need it.

public static int go (String word1, char letter1){

//Your code will go here

}
