# Class Based DSU
-Using Path Compression to get the best time complexity O(1)
-Using Union Rank to keep track of changes using parent(p) O(logN)

* Class based DSU : Path Compression O(1) and Union Rank O(logN)

* made changes to satisfy the meets of the PR

changes made to satisfy the needs of the PR
- used base lib instead of <bits/stdc++.h>
- changed all stdin's and included pre-declared test cases

* removed stdin for testing

* changed file name from upper case to lower case

* made necessary changes

* Delete DSU_union_rank.cpp

* Delete DSU_path_compresssion.cpp

* added explicit to contructors, return 0, n=dec

* Delete dsu_path_compresssion.cpp

* added documentations, to match the typical structure

Added @brief @details @author @param @returns
