How does Radix Sort work?
Algorithms like Radix Sort: https://memory-graph.com/#codeurl=https://raw.githubusercontent.com/bterwijn/memory_graph/refs/heads/main/src/radix_sort.py×tep=0.2&play
are much easier to understand when you can see every intermediate step.Using 𝗺𝗲𝗺𝗼𝗿𝘆_𝗴𝗿𝗮𝗽𝗵: https://github.com/bterwijn/memory_graph#readme
you can watch how Radix Sort repeatedly applies stable Counting Sort, sorting the least significant digit up to the most significant digit in turn.Radix Sort is be very efficient, with time complexity O(n · d), where 'n' is the number of values and 'd' is the number of digits.

This Hash_Map (Hash_Table) is a Python implementation similar to 'dict'. The demo visualizes:
- adding key–value pairs
- rehashing
- lookup by key
- iterating over keys -
