Java:

lastMletters:

Return a string consisting of the last m letters in the list, where m is a parameter

Precondition: the list has at least m nodes Examples: ["ababcdefb"].lastMletters(2) == "fb" ["ababcdefb"].lastMletters(4) == "defb" You can write this iteratively or recursively ---- ** you should only have one loop or recursive helper. **

You may not use any methods from the String class except length

Suggestion: start with an empty string and concatenate chars to it Concatenation example: String x = "Jim"; x = x + 'q'; // adds 'q' on to the right end of "Jim"

public String lastMletters ( int m) {

return "WRONG!"; //TODO 3: fix this }
