- Use python to implement circular array. Using the three properties: o implement the queue interface using a circular array . . array Array object, initialized capacity front_index-int, index where you dequeue back_index-int, index where you enqueue Don't add or use other properties other than the three above. Wrap - around: set index back to 0 after the limit has been exceeded. Implement size, enqueue (), dequeue (). front () Size property - compute using front_index and back_index Must have two cases: Case 1: front_index <= back_index (normal) Case 2: back_index < front_index (wrap-around) enqueue(item): front (): add item to the next available array cell update back_index: wrap-around if exceeds index limit Before array becomes full (one empty slot left), create a bigger array with 2x capacity (note: don't use expand) Copy current queue items to bigger array (make sure you keep the same queue order) Case 1: front_index < back_index (normal) Case 2: back_index < front_index…Person receives text (string) messages on his/her phone. Message memory of a phone is very limited. A buffer is provided for storing messages when phone memory gets full. Message from buffer is loaded into phone memory when space is available. Messages are moved from buffer to phone in such a way that first received message is viewed first on screen. Implement buffer only using array. question solved in data structureThe implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
- Heapsort has heapified an array to: 76 62 40 32 30 and is about to start the second for loop. What is the array after each loop iteration? i= 4: Ex: 86, 75, 30 i = 3: i = 2: i= 1:Implement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation.

I have the data set file , but I cannot upload it in here. Kindly help me with the code. ...Why is it giving me an error and what do I have to change? PYTHON # Problem 2# Implement a hashtable using an array. Your implementation should include public methods for insertion, deletion, and# search, as well as helper methods for resizing. The hash table is resized when the max chain length becomes greater# than 3 during insertion of a new item. You will be using linear chaining technique for collision resolution. Assume# the key to be an integer and use the hash function h(k) = k mod m where m is the size of the hashtable. You can use# python list methods in your implementation of the chain or you can also use your linked list implementation from# coding assignment 2, problem 1.

You are given a two-dimensional array with 6 rows and 6 columns - 36 elements with O value, that represent empty theater seats. All 36 tickets for session were sold, so you need to identify all of the seats with value 1. Write a program that replaces all O values in the given array, by 1 and outputs the resulting matrix. Use nested for-loops to iterate over two-dimensional matrix.
