Evaluate Division

Understand how to use the union find data structure to efficiently evaluate division queries given variable relationships. Learn to interpret equations as graph edges and compute division results or determine if a query is unsolvable. Practice implementing this approach in code to solve connectivity problems with real number values.

We'll cover the following...

Statement

We are given three arrays:

  1. equations: Here, each equations[i] represents a pair of variables [a[i], b[i]], where each  ...
