Explanation

- The **Disjoint-set** (or **Union-Find**) data structure is used to efficiently manage a collection of disjoint sets. It supports two main operations: **find** (finding the representative or leader of a set) and **union** (merging two sets).

  • Steps

    • Find operation: Find the representative (or parent) of an element, typically using path compression for efficiency.
    • Union operation: Combine two sets by linking the root of one set to the root of the other, using union by rank or size for efficiency.
  • Time Complexity

    • Time complexity: O(α(n)), where α is the inverse Ackermann function, which grows extremely slowly, almost constant for all practical purposes.
