4. Disjoint Set Operations: Compressing Find
Which best describes the disjoint set operation Compressing Find
A) Add all keys along the path from given node to root and store in the root
B) Add all keys along the path from root to given node and store in the given node
C) Make each node along the path from given node to root point to the root
D) Make each node along the path from root to given node point to the given node
E) Make all leaf nodes point to the root
F) Make all nodes point to the root
1.
The pre-sorting takes O(ElogE) time
The main part takes O(logV)
so the time oto pre sort dominates
So option A is correct
2.
MAKE SET(V), FIND SET(V), UNION(E)
So option B is correct
3.
Inverse ackernann has a slow growth rate
The growth rate is linear
So option C is correct
4.
Make each node along the path from given node to root point to the root
So option C is correct

Powers of Adjacency Matrix Which is true of an Adjacency Matrix of a directed graph raised to the k-th power (A^k) A) A^k [i][j] = 1 if there is an edge of length k from vertex i to vertex j B) A^k [i][j] = 1 if there...
1 1 point Consider the following algorithm for factoring an integer N provided as input (in binary): For i = 2 to [VN.17 i divides N, then output (i, N/). Which of the following statements is true? This algorithm is correct, but it runs in exponential time. This algorithm is not correct, because it will sometimes fail to find a factorization of Neven if N is composite This algorithm runs in sub-linear time, and always factors N it Nis composite...
In this assignment you’ll implement a data structure called a trie, which is used to answer queries regarding the characteristics of a text file (e.g., frequency of a given word). This write-up introduces the concept of a trie, specifies the API you’re expected to implement, and outlines submission instructions as well as the grading rubric. Please carefully read the entire write-up before you begin coding your submission. Tries A trie is an example of a tree data structure that compactly...
