Use put, get and remove buttons. For keys only lowercase english letters with spaces are allowed.
https://buttondown.email/cassidoo/archive/ada0f77f-5743-4c62-890b-199c25b98ac0 This week’s question: Design a hashmap without using any built-in libraries. You should include the following functions: put(key, value): Insert a (key, value) pair into the hashmap. If the value already exists, update the value. get(key): Returns the value to which key is mapped, or -1 if this map contains nothing for key. remove(key): Remove the mapping for the value in key if it exists.
