Task specification

POST: /api/multiply Takes two paramaters number and times. Returns number multiplyed on itself times times.

POST: /api/group Takes one parameter words which recieves words divided by comma. In the end it groups words by range from 2nd to 4th letter of the word. Example: ( word, lord, master, keys, foot, loot) word and lord have same letters on positions 2-4 (ORD), foot and loot has (OOT). In the end we return grouped words as list of lists -> [ [word, lord], [foot, loot], [keys], [master] ]

POST: /api/serialize Serialize text, sent as text parameter. Serialization is simple. From text “hello -> brave -> new world” we recieve “{‘hello’: {‘brave’: {‘new world’: ‘’}}}” Apply few tests to check unexpected situations and program's logic.
