Problem statement

Given two strings wordA and wordB, return true when they are anagrams of each other and false otherwise.

The comparison is case-insensitive. Anagrams must contain the same letters with the same multiplicities, but the letters may appear in any order.

Function

isAnagram(wordA: String, wordB: String) → boolean

Examples

Example 1

wordA = "Drier"wordB = "Rider"return = true

After ignoring case, both words contain one d, one e, one i, and two r letters.

Example 2

wordA = "hello"wordB = "world"return = false

The two words have different letter counts, so they are not anagrams.

Constraints

wordA and wordB are defined and may be empty.
Each string contains only uppercase and lowercase English letters.
0 ≤ wordA.length, wordB.length ≤ 30.
