Find and Union Operation on Disjoint Sets

The Disjoint Set data structure supports Find and Union operations for managing disjoint sets. The Find operation identifies the representative of a set, while the Union operation merges two sets by connecting their representatives. In the provided Python implementation, the find() method recursively traverses the parent array, and the unite() method links the roots of two sets. This implementation can lead to linear time complexity due to skewed tree structures. The worst-case scenario demonstrates how sets may become linked lists.
