Interrupts are system wide events that stops the execution of a currently running process. Examples of interrupts include (but are not limited to) mouse clicks, process termination, key presses, etc. Some interrupts are considered as more important to be handled first then the others. For example, a hardware interrupt such as hard drive read operation has lesser priority than a memory read. In this way, the most appropriate data structure for representing of such events is the priority queue. Demonstrate by writing an

- Write the code in python programming for the below problem. Introduction One useful data point in detecting fraud is the account history of a customer. For an account, we receive notification of purchases and, sometimes, reports of fraud. Typically, a prior report of fraud for an account would increase the perceived risk of fraud on future transactions. Similarly, a history of non-fraudulent purchases for an account would decrease the risk of fraud. A credit card holder has 90 days to report any fraudulent transactions with the card. So if an account has purchases over 90 days old and no reports of fraud, we assume that these older purchases were not-fraudulent. Problem Description The purpose of this programming problem is to determine the status of a customer account history at the time a new purchase is made. The input is a sequence of customer account events, in chronological order. Each event has three fields, all of which are of string type ,, For example:…arrow_forwardCrossover and Mutation The two main operations in evolutionary computing are crossover and mutation. Crossover works like this: Randomly choose two parents from the population. Let’s say these: Parent 1: T F T F T T F Parent 2: T T T F F T T Those two parents will create a child whose DNA is related to the parents’. It works like this: for each of the seven genes in the chromosome, we will randomly pick a number between 1 and 10 and use it to choose which parents’ value the child will get. If the random number is 1 through 5, we will use Parent 1’s included value for the child; if it is 6…arrow_forwardDemonstrate Recursion Assignment Instructions Overview The programs we’ve discussed so far are generally structured as methods that call one another in a hierarchical manner. For some problems, it’s useful to have a method call itself—this is known as a recursive method. Such a method can call itself either directly or indirectly through another method. Recursion is an important topic discussed at length in upper-level computer-science courses. Instructions Write a recursive method printArray() that displays all the elements in an array of integers, separated by spaces. The array must be 100 elements in size and filled using a for loop and a random number generator. The pseudo-code for this is as follows: //Instantiate an integer array of size 100 //fill the array For (int i=0; i<array.length; i++) Array[i] = random number between 1 and 100 inclusive printArray(integer array); For this assignment make sure that your screen shots show your program running and that your runtime…arrow_forward
- Personal project Q5. This question is concerned with the design and analysis of recursive algorithms. You are given a problem statement as shown below. This problem is concerned with performing calculations on a sequence A of real numbers. Whilst this could be done using a conventional loop-based approach, your answer must be developed using a recursive algorithm. No marks will be given if your answer uses loops. FindAverageAndProduct(a1, ...., an) such that n > 1 Input: A sequence of real values A = (a1, ...., an) Output:, A 2-tuple (average, product) containing the average (average) of all the values and the product (product) of all the values of the elements in A. Your recursive algorithm should use a single recursive structure to find the average and product values, and should not use two separate instances of a recursive design. You should not employ any global variables. (a) Produce a pseudo code design for a recursive algorithm to solve this problem. (b) Draw a call-stack…arrow_forwardPersonal project Q5.

(Efficient Recurrence Relations Calculation) At slide 54 of Lecture 10, we have seen aconcurrent implementation of classical Fibonacci recurrence. This is: fun {Fib X} if X==0 then 0 elseif X==1 then 1 else thread {Fib X-1} end + {Fib X-2} end end By calling Fib for actual parameter value 6, we get the following execution containing several calls ofthe same actual parameters.For example, F3, that stands for {Fib 3}, is calculated independently three times (although it providesthe same value every time). Write an efficient Oz implementation that is doing a function call for a givenactual parameter only once.Consider a more general recurrence relation, e.g.:F0, F1, ..., Fm-1 are known as initial values.Fn = g(Fn-1, ..., Fn-m), for any n ≥ m.For example, Fibonacci recurrence has m=2, g(x, y) = x+y, F0=F1=1arrow_forward
- In the study of formal languages state-transition diagrams are often usedto visualize changes in a machine’s configuration as it acts on input. To visualize amachine’s configuration think of its parts: Commonly a finite set of states, a finiteinput alphabet Σ, Perhaps storage devices (a stack, input/output tapes). The states arepictured as named circles sometimes decorated with symbols to denote special states,e.g. start and final states. Changes in configuration are denoted by labeled edges andperhaps changes in storage.1. Describe how edges are labeled and their meaning for finite state machines.2. Describe how edges are labeled and their meaning for pushdown automata.3. Describe how edges are labeled and their meaning for Turing machines.arrow_forwardDesign and implement a recursive program(in java) to determine and print the Nth line of Pascal's triangle, as shown below.

A certain computer algorithm executes four times as many operations when it is run with an input of size n as when it is run with an input of size n – 1. Here, n > 1 is an integer. When the algorithm is run with an input of size 1, it executes 12 operations. How many operations does the algorithm execute when it is run with an input of size 5? How many operations does the algorithm execute when it is run with an input of size n?arrow_forward
