Check for Anagrams

Create a function that takes two strings and returns either True or False depending on whether they're anagrams or not.

Examples

is_anagram("cristian", "Cristina") ➞ True

is_anagram("Dave Barry", "Ray Adverb") ➞ True

is_anagram("Nope", "Note") ➞ False

Notes

• Should be case insensitive.
• The two given strings can be of different lengths.
