One way to solve this is by converting the digits into words. This is done by determining how many times the digit repeats, and then combining the word with the number that corresponds to that number. This method proves particularly useful when dealing withphone numbers in letters. It can be...
Given a string containing digits from2-9inclusive, return all possible letter combinations that the number could represent. Return the answer in any order. A mapping of digit to letters (just like on the telephone buttons) is given below. Note that 1 does not map to any letters. Input: di...
