- nterruptions are occurrences that cause the usual flow of execution to be interrupted. Give five distinct occurrences that might lead to a disruption.Write a program that does: if Port2.2 is 0, takes the 35, 86, 70, 58, 25, 46 values in order from a lookup table in a loop and send them to the port2. The values will be taken from a lookup table. Answers that do not use a lookup table are invalid.You are tasked with the development of an E-Scooter ride-sharesystem. It allows registered commuters to approach an idle E-Scooter andreserve it, following which they use the E-Scooter to commute a certaindistance (that is not known prior to use). Finally, after the commuter reachestheir destination, they end the ride, which prompts an automaticcomputation of the ride fees. which is automatically debited using thecommuters registered payment details.
- You are the sysadmin for a big tech company, and you have to estimate the amount of servers you need to handle some long-running jobs. One server can handle only one job at once. One job can only be executed by one server at once. Once a server has finished executing its current job, it can be reassigned to a new job. Given an array of time intervals intervals where intervals[i] = [starti, endi], representing the start and end time for a particular job that needs to be executed, return the minimum number of servers required to run all jobs. Constraints: 1 <= intervals.length <= 104 0 <= starti < endi <= 106 Function definition for Java: public int minMeetingRooms(int[][] intervals) { // Your code here } Function definition for Python: def minMeetingRooms(self, intervals: List[List[int]]) -> int: #Your code here Announced Test Cases: Input: intervals = [[0,30],[5,10],[15,20]] Output: 2Explanation: We need one server for the job that starts at 0. For the job…Implement a blog server in C 1. Implement get of all posts (GET /posts), and individual post (GET /post/1) 2. Implement creation of post (POST /posts). Allow the user to enter their name, but check that they are a valid user in db. Do error checking! The user should not specify the post id; that should come from the database. 3. Write three html files to test this; serve them with the blog server: index.html shows the list of posts with a link to each. post.html shows a post. publish.html allows the creation of a new post. Link these together as a user would expect!Assume we wish to resize an existing hash table because the current hash table is becoming too small for the application. Without writing code briefly describe the process of resizing a hash table by "copying" the old data to the new hash table. What is the expected complexity of your process using Big-O notation. Justify your complexity measure. An example of a hash table before resizing is given.
- Suppose the database contains n RnaSequence objects, in a random order. What is the average case big-Oh for the number of RnaSequence comparisons used when creating a BST by adding the RnaSequence objects to the BST in the order they appear in the database? You can assume that all items in the database are uniquethere are no repeated RnaSequence values. Select one: o O(n²logn) O ((nlogn) o (n²) O (2n) о О(nlogzn) O (2n²) O (logn) O O(log,n) O O(n)Implement a Restful API (with receiving data file) with all HTTP methods, using python flask framework having any scenario that contain a JSON format data of at-least 10 key-value pairs. Your solution file contains Complete code snippet of your Restful API All routes output screens (in postman tool) All server responses screens (clearly shown GET/PUT/DELETE requests and respective HTTP codes) Language : Python Software : Mentioned in Question Paste Screenshots AlsoSuppose you’re consulting for a bank that’s concerned about fraud detection, and they come to youwith the following problem. They have a collection of n bank cards that they’ve confiscated, suspectingthem of being used in fraud. Each bank card is a small plastic object, containing a magnetic stripe withsome encrypted data, and it corresponds to a unique account in the bank. Each account can have manybank cards corresponding to it, and we’ll say that two bank cards are equivalent if they correspond to thesame account.It’s very difficult to read the account number off a bank card directly, but the bank has a high-tech “equivalence tester” that takes two bank cards and, after performing some computations, determines whether theyare equivalent.Their question is the following: among the collection of n cards, is there a set of more than n/2 of themthat are all equivalent to one another? Assume that the only feasible operations you can do with the cardsare to pick two of them and plug them…
- Write a performance driver program that uses put() tofill a symbol table, then uses get() such that each key in the table is hit an average often times and there is about the same number of misses, doing so multiple times onrandom sequences of string keys of various lengths ranging from 2 to 50 characters;measures the time taken for each run; and prints out or plots the average running times.Select a states that is not q2 from the GNFA to delete. Then, create a new GNFA for the deleted state that is equivalent to M but does not have the selected state.Implement a dynamically resizable hash table to store people’s names and Social Security numbers. Use the extraction method with division using the last four digits of the Social Security number. Use an initial table size of 31 and a load factor of 0.80. Use open addressing with double hashing using an extraction method on the first three digits of the Social Security number.
