Instructions + +An anagram is a rearrangement of letters to form a new word: for example `"owns"` is an anagram of `"snow"`. +A word is not its own anagram: for example, `"stop"` is not an anagram of `"stop"`. + +Given a target word and a set of candidate words, this exercise requests the anagram set: the subset of the candidates that are anagrams of the target. + +The target and candidates are words of one or more ASCII alphabetic characters (`A`-`Z` and `a`-`z`). +Lowercase and uppercase characters are equivalent: for example, `"PoTS"` is an anagram of `"sTOp"`, but `StoP` is not an anagram of `sTOp`. +The anagram set is the subset of the candidate set that are anagrams of the target (in any order). +Words in the anagram set should have the same letter case as in the candidate set. + +Given the target `"stone"` and candidates `"stone"`, `"tones"`, `"banana"`, `"tons"`, `"notes"`, `"Seton"`, the anagram set is `"tones"`, `"notes"`, `"Seton"`. + +## Source + +### Created by +
