Correct answer will be upvoted else downvoted. Computer science. You have a card deck of n cards, numbered through and through, I. e. the top card has list 1 and base card — file n. Each card has its tone: the I-th card has shading artificial intelligence. You should handle q inquiries. The j-th inquiry is depicted by integer tj. For each inquiry you ought to: track down the most elevated card in the deck with shading tj, I. e. the card with least list; print the situation of the card you found; assume the card and position it on top of the deck. Input The primary line contains two integers n and q (2≤n≤3⋅105; 1≤q≤3⋅105) — the number of cards in the deck and the number of questions. The subsequent line contains n integers a1,a2,… ,an (1≤ai≤50) — the shades of cards. The third line contains q integers t1,t2,… ,tq (1≤tj≤50) — the inquiry tones. It's reliable that inquiries ask just shadings that are available in the deck. Output Print q integers — the…
The following functions/statements are useful to solve the probler: • The pow function from the library: e.g. pow(x.y) gives the value of x • The rand( ) function from the library: rand( ) gives a random integer between 0 and RAND_MAX, where RAND_MAX is a predefined constant integer in C++. When you use rand( ) make sure to include the empty braces (you will understand what they mean later when you learn about C++ functions). The srand(time(0)); statement at the beginning of main which requires adding the library. This statement is needed if you want the program to give different random values for different runs. The use of srand(time(0)) is optional; i.e. no grades will be deducted if you do not include it.

9. Simplify the following Boolean functions, using three-variable maps:
Let Ax = {a,b,...,z,—}, |Ax| = 27, denote alpahabet of letters in English text where - represents the space character between words. Let Px = {P₁, P2,..., P27} denote the probability of letters. 1) Estimate pi, by parsing the text "All Systems Red' by Martha Wells. To do this you have to parse the letters in the book and form a character vector x = = [1, 2,..., TN] where N is the number of letters in the book. (Turn all uppercase letters into lowercases and ignore the characters that are not in Ax). You may use Matlab or Python. Then you can estimate p; by its frequency in the text #(x₁ = ai) N where #(i = a;) denotes the number of times ï¿ = a¿ in x. Pi = (1)
Determine the appropriate value for the decision parameter p to use in the Bresenham's circle drawing procedure. The instructions that Bresenham developed for drawing a circle are presented in this article in the form of an algorithm that may be followed step by step.
Size of sample space L.A An eleven-sided dice is rolled and a five-sided is tossed. Considering this as a probability experiment, what is the size of the sample space? An Event In the context of the probability experiment just described. Consider the event in which the two numbers on the two dice add to 12. What is the size of this set? 1.B Probability of an event (1/2) What is the probability of the event just described? Write your answer as a fraction of integers. For example, if the answer were 17/20 then enter 17/20 with no spaces or other symbols. You may reduce the fraction by cancelling factors common to the numerator and denominator but you do not need to do this. 1.C Probability of an event (2/2) What is the probability that upper faces on the two dice add to fifteen? Write your answer as a fraction of integers. For example, if the answer were 17/20 then enter 17/20 with no spaces or other symbols. You may reduce the fraction by cancelling factors common to the numerator and…

Question 17 And question 19 Thanks in advance ?
Computer Science Investing in stocks is a way to create assets that are supposed to provide financial security over time. In solving this problem, we assume that an investor buys several shares of stock at a certain price. These shares are going to be sold later on for a different price. Obviously, if the selling price is higher than the acquisition price, the investor makes a profit, registering capital gain. If the shares are sold at a lower price, the investor has a loss, which marks a negative capital gain. This whole process is done over a period of time, and you are required to create a scenario for buying and selling shares. The assumption is that the investor sells shares in the order in which they were purchased. The goal is to calculate the capital gain over time. Suppose that you buy n shares of stock or mutual fund for d dollars each. Later, you sell some of these shares. If the sale price exceeds the purchase price, you have made a profit—a capital gain. On the other…
