In a disjoint set data strücture, the union operation is done using ranks. That is, the lower rank is added to the larger one. If equal, the right is added to the left. For example, in union (1, 2), if the ranks of the two sets are equal, the set of 2 is added to 1. Accordingly, after the elements 1, 2, 3, 4, 5, 6, 7, 8, 9 are set with make-set,What is the height of the tree resulting from operations union(1,2), union(3,4), union(4,5),union(1,7), union(3,6), union (8,9), union (1,8), union(3,1)? 1 2 3 4 5

Consider the perfume dataset in the file, it contains the strength of the smell of 20 perfumes measured by an odor meter throughout 25 seconds, so each second (column) is a new measurement. Write a program to group these perfumes based on the similarity in the strength of their smell. You should use k-means clustering algorithm. The final output of your program should show k lists of perfumes, and show outlier perfume’s records (if exists).

Correct answer will be upvoted else downvoted. Computer science. Vanya needs to count the number of unacceptable integers for the picked set S. Vanya plans to attempt various sets S. He needs you to compose a program that tracks down the number of inadmissible integers for the underlying set S, and after each change to the set S. Vanya will make q changes to the set, and each change is one of the accompanying two sorts: add another integer a to the set S, or eliminate some integer a from the set S. Input The principal line contains two integers n, q (1≤n,q≤200000) — the size of the underlying set S and the number of changes. The following line contains n particular integers s1,s2,… ,sn (1≤si≤1013) — the underlying components of S. Every one of the accompanying q lines contain two integers ti, computer based intelligence (1≤ti≤2, 1≤ai≤1013), depicting a change: In the event that ti=1, an integer simulated intelligence is added to the set S. It is ensured that…

Draw the Weighted Quick Union object on 0 through 10, that results from the following connectconnectcalls. Do not use path compression. Note that if we connect two sets of equal weight, by convention we make the set whose root has a smaller number the parent of the other. We use the convention that if an element is the root of the set, its array value is the weight of the set negated. connect(0, 1); connect(2, 3); connect(9, 5); connect(5, 7); connect(7, 1); connect(4, 2); connect(3, 1);
Implement the RandomizedSet class: RandomizedSet() Initializes the RandomizedSet object. bool insert(int val) Inserts an item val into the set if not present. Returns true if the item was not present, false otherwise. bool remove(int val) Removes an item val from the set if present. Returns true if the item was present, false otherwise. int getRandom() Returns a random element from the current set of elements (it's guaranteed that at least one element exists when this method is called). Each element must have the same probability of being returned. You must implement the functions of the class such that each function works in average O(1) time complexity. Example 1: Input ["RandomizedSet", "insert", "remove", "insert", "getRandom", "remove", "insert", "getRandom"] [[], [1], [2], [2], [], [1], [2], []] Output [null, true, false, true, 2, true, false, 2] Explanation RandomizedSet randomizedSet = new RandomizedSet(); randomizedSet.insert(1); // Inserts 1 to the set.
