Chapter 6, Problem 6.28E
(Duplicate Elimination) In Chapter 12, we explore the high-speed binary search tree data structure. One feature of a binary search tree is that duplicate values are discarded when insertions are made into the tree. This is referred to as duplicate elimination. Write a

1.""Implementation of the Misra-Gries algorithm.Given a list of items and a value k, it returns the every item in the listthat appears at least n/k times, where n is the length of the array
By default, k is set to 2, solving the majority problem.
For the majority problem, this algorithm only guarantees that if there isan element that appears more than n/2 times, it will be outputed. If thereis no such element, any arbitrary element is returned by the algorithm.Therefore, we need to iterate through again at the end. But since we have filtredout the suspects, the memory complexity is significantly lower thanit would be to create counter for every element in the list.
For example:Input misras_gries([1,4,4,4,5,4,4])Output {'4':5}Input misras_gries([0,0,0,1,1,1,1])Output {'1':4}Input misras_gries([0,0,0,0,1,1,1,2,2],3)Output {'0':4,'1':3}Input misras_gries([0,0,0,1,1,1]Output None""".expl.

Array Indexing: Knowing the basics of array indexing is
important for
analysing and manipulating the array object. NumPy offers
many ways to do
array indexing.
O slicing: Just like lists in python, NumPy arrays can be sliced.
As arrays
can be multidimensional, you need to specify a slice for each
dimension of
the array.
O Integer array indexing: In this method, lists are passed for
indexing for
each dimension. One to one mapping of corresponding
elements is done to
construct a new arbitrary array.
O Boolean array indexing: This method is used when we want
to pick
elements from array which satisfy some condition
(Algebra: perfect square
)
Write a program that prompts the user to enter an integer
m
and find the smallest integer
n
such that
m * n
is a perfect square.
(Hint: Store all smallest factors of
m
into an array list.
n
is the product of the factors that appear an odd number of times in the array list.
For example, consider
m
= 90, store the factors 2, 3, 3, 5 in an array list. 2 and 5 appear an odd number of times in the array list. So,
n
is 10.)
Sample Run 1
Enter an integer m: 1500
The smallest number n for m x n to be a perfect square is 15
m x n is 22500
Sample Run 2
Enter an integer m: 63
The smallest number n for m x n to be a perfect square is 7
m x n is 441

- Java Programming [ Using Array] - 1arrow_forwardplease code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes Create a program that takes a password string from the user and encrypts the letters to go up or down the alphabet using a triple-number key. The amount up or down for the encryption of the alphabetical characters will depend on the input from the user. Input for the encryption key integers will be -25 ≤ key ≤ 25.For example, ‘CHICKEN’ with a 1, 2, -3 would be C up 1 to D, H up 2 to J, I down 3 to F,then C up 1 to D, K up 2 to M, E down 3 to B, and N up 1 to O. Thus the encryption becomes ‘DJFDMBO’.arrow_forward[] [] partite_sets In the cell below, you are to write a function "partite_sets (graph)" that takes in a BIPARTITE graph as its input, and then returns a single list whose two entries are the partite sets of the graph as lists (the order of the sets outputed does not matter). After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (partite_sets({"A" : ["B", "C"], "B" : partite_sets({"A" : ["B", "C"], "B" : ["A"], "C" : ["A"]}), ["A", "D"], "C" : ["A", "D"], "D" : ["B", "C"]})) This should return [["B","C"], ["A"]] [["A","D"], ["B","C"]] (the order in which the entries appear does not matter) Python Pythonarrow_forward
