- python only** define the following function: This function must set the value of a task in a checklist to True. It will accept two parameters: the checklist object to add to, and the name of the task to mark as completed. In addition to changing the task value, it must return the (now modified) checklist object that it was given. if the task name provided is not in the checklist, this function must print a specific message and must return None. Define completeTask with 2 parameters Use def to define completeTask with 2 parameters Use a return statement Within the definition of completeTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of completeTask with 2 parameters, do not use any kind of loop.1. Which of the following statements are correct? (Select all that applies.) Group of answer choices "ABCDEFG" and "XZACKDFWGH" have "ACDG" as a longest common subsequence. If X is of length n, then it has 2^n subsequences. There is a dynamic programming approach to the longest common subsequence problem. 2. What is the correct syntax to create a NumPy array? Group of answer choices np.object([1, 2, 3]) np.createArray([1, 2, 3]) np.array([1, 2, 3]) 3. What is the correct Pandas function for loading CSV files into a DataFrame? Group of answer choices csv_read() read_csv() loadcsv()Scheduling: Select all of the following statements that are true. The service time is also known as the CPU burst. The minimum average waiting time for a given set of processes is reached when the Shortest Job First (SJF) scheduling algorithm is applied. The method of exponential averaging can be used to increase the priority of jobs according to their waiting time. Round Robin (RR) scheduling can lead to starvation. Priority Inversion means that high-priority processes can be delayed or blocked by lower-priority processes.
- Build the loop function by R-studio build a function that assigns each student to be evaluated 4 other students’ projects. The function is such that each student must have 4 classmates evaluating projects without replacement. the outcome of a random selection process or it can be the outcome of a deterministic process (meaning that every time you run the function, it gives the same output).1) Let A = {x EN: x - 16 = 0}. Rewrite A in roster notation. |A| = 2) Let B = {x E Z : x² – 16 = 0}. Rewrite B in roster notation. \B| = 3) Let C = {x E Z : x² – 48 = 0}. Rewrite C in roster notation. |C| =Topical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information One statistic of interest to many researchers is the median of a set of data. The median is the value in the middle. (This is NOT the average, mind you.) Being in the middle, of course implies that the data are in order (sorted). If there are an odd number of data items, the middle is simple to find. If there are an even number of data items, you are supposed to take the average of the two middle values. You'll need to find the median of a set of data from a file. You don't know how many data are in the file, of course. You'll have to count the data, then read them in to sort, then find the median, and finally print it (the median) out. Do NOT use any more memory than is necessary!!
- python only** define the following function: This function must return the task status for a particular task from a checklist. These examples for taskStatus demonstrate how it works. As with addTask, there's the possibility that the task specified is invalid (in this case, because it isn't in the checklist). In that case, taskStatus must print a specific message ("That task does not exist."), and must return None. Define taskStatus with 2 parameters Use def to define taskStatus with 2 parameters Use a return statement Within the definition of taskStatus with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of taskStatus with 2 parameters, do not use any kind of loop.: Find the weakest precondition for the following code. Show all intermediate conditions. Simplify your answer Question 4. as much as possible. { } // This is the weakest precondition. Please fill in. x++; { } // This is an intermediate condition.

We should signify the Manhattan distance between them as d(p,q)=|xp−xq|+|yp−yq|. Suppose that three focuses p, q, r structure an awful triple if d(p,r)=d(p,q)+d(q,r). Suppose that an exhibit b1,b2,… ,bm is acceptable in case it is difficult to pick three particular records I, j, k with the end goal that the focuses (bi,i), (bj,j) and (bk,k) structure an awful triple. You are given a cluster a1,a2,… ,an. Workout the number of good subarrays of a. A subarray of the cluster an is the exhibit al,al+1,… ,ar for some 1≤l≤r≤n. Note that, as indicated by the definition, subarrays of length 1 and 2 are acceptable. Input The primary line contains one integer t (1≤t≤5000) — the number of experiments. The main line of each experiment contains one integer n (1≤n≤2⋅105) — the length of cluster a. The second line of each experiment…
- Memory Allocation: Select all of the following statements that are true. The basic idea of contiguous allocation is that each process is contained in a single contiguous section of memory. When using a single-partition allocation scheme, the main memory is usually divided into three partitions. Memory partitioning schemes allow for multiprogramming. When applying the multiple-partition allocation scheme "Fixed Partitions", all partitions always have the same size. When applying the multiple-partition allocation scheme "Variable Partitions", the FirstFit allocation strategy performs best in practice. The Buddy system is prone to internal fragmentation.INSTRUCTIONS: Write a C++ script/code to do the given problems. MOVIE PROBLEM: Write a function that checks whether a person can watch an R18+ rated movie. One of the following two conditions is required for admittance: The person is atleast 18 years old. • They have parental supervision. The function accepts two parameters, age and isSupervised. Return a boolean. Example: acceptIntoMovie(14, true) → true acceptIntoMovie(14, false) → falseFill in the blanks below. Assume user supplies the value of n. Line # Code 2 do { 3 print x 4 X=x+1 while (n >= x) The number times the print operation in Line 3 is executed is The number of times the addition operation in Line 4 is executed is The number of times the comparison operation in Line 5 is executed is The running time f(n) of this code is e ).
