Given a string containing digits from 2-9 inclusive, return all possible letter combinations that the number could represent. A mapping of digit to letters (just like on the telephone buttons) is given below. Note that 1 does not map to any letters.
Given a list of sorted characters letterscontaining only lowercase letters, and given a target letter target, find the smallest element in the list that is larger than the given target. Letters also wrap around. For example, if the target is target =
Given a string S, we can transform every letter individually to be lowercase or uppercase to create another string. Return a list of all possible strings we could create. Examples: Input: S = "a1b2" Output: ["a1b2", "a1B2",
A character is unique in string S if it occurs exactly once in it. For example, in string S = "LETTER", the only unique characters are "L" and "R". Let's define UNIQ(S) as the number of unique characters in string S. For exam
