Return to List

Solve: plus Out

Imported By: Geoffrey Challen
/ Version: 2021.7.0

Given a non-null String main and a non-empty String word, return a String where all characters in main have replaced by pluses ("+"), except for appearances of word which are preserved unchanged. So if main is "12xy34" and word is "xy" you should return "++xy++".

String plusOut(String input, String word) {
return ""; // You may need to remove this starter code
