(Computation) Among other applications, Pascal’s triangle (see Figure 7.22) provides a means of determining the number of possible combinations of n things taken r at a time. For example, the number of possible combinations of five people (n = 5) taken two at a time
Each row of the triangle begins and ends with 1. Every other element in a row is the sum of the element directly above it with the element to the left of the one above it. That is,

- (True/False): A segment descriptor does not contain segment size informationarrow_forward(Data Structures and Algo C++ Weiss 4th ed - ch7.40): The following divide-and-conquer algorithm is proposed for finding the simultaneous maximum and minimum: If there is one item, it is the maximum and minimum, and if there are two items, then compare them, and in one comparison you can find the maximum and minimum. Otherwise, split the input into two halves, divided as evenly as possibly (if N is odd, one of the two halves will have one more element than the other). Recursively find the maximum and minimum of each half, and then in two additional comparisons produce the maximum and minimum for the entire problem. In C++, find a function which will take in a vector and solve the problem, producing a vector of two elements, the min and max.arrow_forwardQ1} write program to calculate the resistance, R, to fluid flow a long two pipe is connected where L1-L₂ cote R= L₁ T₂ singe Where k is a constant, L₁, L2 are length of the first pipe and second pipe respectively, r₁, r2 are the radius of the first pipe and second pipe respectively.

- (Check test scores) The answers to a true-false test are as follows: T T F F T. Given a two-dimensional answer array, in which each row corresponds to the answers provided on one test, write a function that accepts the two-dimensional array and number of tests as parameters and returns a one-dimensional array containing the grades for each test. (Each question is worth 5 points so that the maximum possible grade is 25.) Test your function with the following data: int score = 0;arrow_forward*Please help in javascript* Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 import java.util.Scanner; public class LabProgram {public static void main(String[] args) {/* Type your code here. */}}arrow_forwardplease code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]arrow_forward
- ## MP (Machine Problem) Details The bulls and cows game is a code-breaking game designed for two or more players. Each player chooses a secret code of 4 digits from 0 – 9. The digits must be all different. The goal of the game is for each player to guess the other player's secret code. The players in turn present their guesses to the opponents. The opponents respond by telling the players: 1. The number of bulls, i.e. the number of matching digits in their right positions, and 2. The number of cows, i.e. the number of matching digits but in different positions. ### Requirements The main goal of this assignment is to develop the bulls and cows game that allows a single player to play interactively against the computer. The game stores two secret codes, one from the player and one from the computer. The player and the computer will try to guess each other’s secret code. Both the player and the computer only have seven attempts for guessing the secret code. If the player enters invalid…arrow_forward2, Towers of Hanoi Problem. (10 points) The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk. Answer the following questions. (1) Determine a state representation for this problem. (4points) (2) What is the size of the state space? (3 points) (3) Supposing K=3, N=4, what is the start state by using your proposed state representation method and what is the goal state?

- (CE2471 Computer architecture and assembly language) Questions Write a program maxarray that computes the double of maximum of values of any given array of length L=7. The computation of the maximum is done in a procedure. For example : if the values in the array are : 14, 5, 85, 17, 9, 1, 47. The result is 170.arrow_forward(Random sentences and story writer) Write an app that uses random-number generation to create sentences. Use four arrays of strings, called article, noun, verb andprepostion. Create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article, noun.As each word is picked, concatenate it to the previous words in the sentence. The words should be separated by spaces. When the sentence is output, it should start witha capital letter and end with a period. The program should generate 10 sentences and output them to a text box. The arrays should be filled as follows:The article array should contain the articles "the", "a", "one", "some" and "any";The noun array should contain the nouns "boy", "girl", "dog", "town", "car";The verb array should contain the past tense verbs "drove", "jumped", "ran", "walked" and "skipped";The preposition array should contain the preposotions "to", "from", "over", "under" and "on";arrow_forwardx4 + 2x3 – 7x2 + 3 = 0 a) One of the root of the equation lies in the range (1.0, 2.0). Find this root in 100 iterations using the bisection method. b) Draw the graph of the function between points (0, 2). Your code should include the following steps: • Write the steps of the bisection function (if, else...) and explain each step. (Explain each step in English or Turkish.) • Your code should calculate the root. • Graphic; Variables of x and y axes should be written, x and y axis names should be written, Series should be written to calculate x axis. Use the linspace() for the x series of the graph and section the range 0-2 into 100 pięces.arrow_forward
