Computer science. You are given a parallel table of size n×m. This table comprises of images 0 and 1. You can make such activity: select 3 distinct cells that have a place with one 2×2 square and change the images in these cells (change 0 to 1 and 1 to 0). Your assignment is to make all images in the table equivalent to 0. You are permitted to make all things considered 3nm activities. You don't have to limit the number of activities. It tends to be demonstrated that it is consistently conceivable. Input The principal line contains a solitary integer t (1≤t≤5000) — the number of experiments. The following lines contain portrayals of experiments. The principal line of the depiction of each experiment contains two integers n, m (2≤n,m≤100). Every one of the following n lines contains a parallel line of length m, depicting the images of the following column of the table. It is…You are given a N*N maze with a rat placed at maze[0][0].

A cell with a value = -1 is an obstacle that cannot be overcome. The goal is to start from cell [0, 0] and reach the last cell [m-1, n-1]. This may be possible by taking several paths. Count the number of these paths. The movement is allowed from cells (i+ 1, j) and (i, j+ 1) only. -1 -1 Provide two solutions, one iterative and one recursive to the above problem.
- Correct answer will be upvoted else downvoted. Computer science. You are given an exhibit a comprising of n (n≥3) positive integers. It is realized that in this exhibit, every one of the numbers with the exception of one are something very similar (for instance, in the cluster [4,11,4,4] all numbers aside from one are equivalent to 4). Print the list of the component that doesn't rise to other people. The numbers in the cluster are numbered from one. Input The main line contains a solitary integer t (1≤t≤100). Then, at that point, t experiments follow. The main line of each experiment contains a solitary integer n (3≤n≤100) — the length of the exhibit a. The second line of each experiment contains n integers a1,a2,… ,an (1≤ai≤100). It is ensured that every one of the numbers aside from one in the an exhibit are something very similar. Output For each experiment, output a solitary integer — the list of the component that isn't equivalent to other people.Given n integers (a₁, az, . an}, let S = a1 + a₂ + ・・・ + an. Suppose that S is even. Design .../ an algorithm that finds a subset of these n integers whose sum is S/2.A palindrome is a sequence that is the same as its reverse. For example, the word "RACECAR" is a palindrome. For this problem we will define an almost palindrome to be a sequence that can be transformed into its reverse with 2 or fewer character additions, deletions, replacements, or swaps. A character swap swaps two adjacent characters. For instance "MARJORAM" can be reversed by swapping the 'J' and the 'O'. In addition, "FOOLPROOF" can be reversed by replacing the 'R' with and 'L' and vice versa. Finally, the word "BONOBO" can be reversed by deleting the final 'O' and reinserting it at the beginning. Devise a dynamic programming algorithm that will determine the number of edits necessary to to transform a sequence into its reverse. a) State this problem with formal input and output conditions. b) State a self-reduction for this problem. c) State a dynamic programming algorithm based off of your self-reduction that computes the minimum number of edits to transform a sequence into its…
- Sorting objects in the real world https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html There are 5000 people living in the town. Every day they have new COVID-19 cases. When people show symptom, they go to the hospital and put themselves in the waiting list for testing. A new person is added at the end of the list. Due to the lack of testing kit, all in the list cannot be tested. Hospital has to sort them and select a few. Since the elderly is very weak to the COVID-19, every midnight the doctors sort the people in the list by their age to decide who is taking the test for the next day depending on the availability of testing kit. Input to the program has the form where the first line indicates how many days they will do the operation. For each day, the input starts with the day number, along with the following patient list where each element represents the name of patients and the age. The input ends with the number of available testing kits. The output display, at…Imagine a ballroom with two kinds of dancers: leaders and followers. Dancers of both kinds wait in two separate queues before entering the dance floor. When a leader arrives, it checks to see if there is a follower waiting. If so, they can both proceed. Otherwise it waits. Similarly, when a follower arrives, it checks for a leader and either proceeds or waits, accordingly. Make sure that the next pair of leader/follower may dance only after the previous pair is done.Write the pseudocode for leaders and followers that enforces these constraints.Modeling the spread of a virus like COVID-19 using recursion. Let N = total population (assumed constant, disregarding deaths, births, immigration, and emigration). S n = number who are susceptible to the disease at time n (n is in weeks). I n = number who are infected (and contagious) at time n. R n = number who are recovered (and not contagiuous) at time n. The total population is divided between these three groups: N = S n + I n + R n There are several hidden assumptions here that may or may not apply to COVID-19, such as a recovered person is assumed to not be able to get the disease a second time, at least within the time window being examined. On week 0 (the start), you assume a certain small number of people have the infection (just to get things going). Everyone else is initially susceptible, and no one is recovered. There are two constants of interest: Let period = time period that it takes for an infected person to recover (recover meaning they become not infectious to…
