We solve LeetCode 706: Design HashMap by building a hashmap from scratch in Python using bucket hashing with separate chaining.

Goal:
Implement these methods
put key, value
get key
remove key

Approach:
Choose a fixed bucket count that is a prime number, for example 769, to spread keys uniformly.
Hash function: key modulo bucket_count.
Each bucket stores a small list of pairs key, value.
put
• Scan the bucket; update value if key exists, otherwise append new pair.
get
• Scan the bucket; return stored value if key exists, otherwise return minus one.
remove
• Scan the bucket; delete the pair if key exists.
