- [Unbalanced Rod] Given a set of n weights {w₁,..., wn} and a rod of length n - 1 inches, we can attach the weights to the rod at hooks placed at one inch distances apart as shown in the figure below. -1". /10 2 3 12 2 4 We can attach a weight to any hook but no two weights can be attached to the same hook and we have to attach all the weights. For any given assignment of weights to hooks, we can compute the location of the center of mass of the rod and the weights according to the following equation (neglecting the weights of the rod and the hooks). where 0 ≤ Pi≤n-1 is the position of weight along the rod. For example, in the figure shown above, the center of mass is computed as C= C = i Wi Pi Σi Wi 10 0+2 1+3·2+4·3+12.4 +2.5 10+2+3+4+12+2 78 33 The problem is to find an assignment of weights to hooks that makes the center of mass as far as possible to the left, i.e., minimize the value of c. Answer the following questions. 1. Describe a greedy algorithm that finds the assignments that…Programing C Just with #include Matrix Addition and Subtraction (Associatively) Write a program that performs matrices addition and subtraction. As shown in the example below, you have to ask the user for the number of rows and number of columns that both matrices should have (they both have to be the same size, that is why you only ask once). You will then ask the user for the values of each matrix. Then, you will print the values that the user inputted, the added values of both matrices, and the subtracted values (matrix 2 should be subtracted from matrix 1). In this challenge Guidelines/steps: • The number of rows and the number of columns should be global variables. • Once you get these two from the user, you should declare your two matrices in main. • Then, from main, you will call function aaa twice; first, you will send matrix 1 and populate it with values inputted by the user. You will call the function a second time, send matrix 2 and populate it. In other words, function aaa…2.a Σ : {c,A,G,T}, L = { w : w = CAG™T™C, m = j + n }. For example, CAGTTC E L; CTAGTC ¢ L because the symbols are not in the order specified by the characteristic function; CAGTT ¢ L because it does not end with c; and CAGGTTC € L because the number of T's do not equal the number of A's plus the number of G's. Prove that L¢ RLs using the RL pumping theorem.
- F(?,?,?)=?′?′?+?′??+??′?′+??′?can you simplify this and draw the diagram of the simplified functionWrite in C++ Alice is trying to monitor how much time she spends studying per week. She going through her logs, and wants to figure out which week she studied the least, her total time spent studying, and her average time spent studying per week. To help Alice work towards this goal, write three functions: min(), total(), and average(). All three functions take two parameters: an array of doubles and the number of elements in the array. Then, they make the following computations: min() - returns the minimum value in the array sum() - returns the sum of all the values in the array average() - returns the average of all the values in the array You may assume that the array will be non-empty. Function specifications: Function 1: Finding the minimum hours studied Name: min() Parameters (Your function should accept these parameters IN THIS ORDER): arr double: The input array containing Alice's study hours per week arr_size int: The number of elements stored in the array Return Value:…Complete the following function using pass-by-reference: void findMax(int &max, int a) which assigns value ‘a’ to ‘max’ if a > max. Write a pseudo-code then implement a program in C language to find the maximum in a sequence of numbers using this function.
- computer science | c++ code | it's not graded. Correct answer will upvoted else downvoted. It is given a non-negative integer x, the decimal portrayal of which contains n digits. You need to shading every its digit in red or dark, so the number shaped by the red digits is separable by A, and the number framed by the dark digits is detachable by B. No less than one digit should be shaded in every one of two tones. Consider, the include of digits hued in red is r and the include of digits hued in dark is b. Among all potential colorings of the given number x, you need to output any to such an extent that the worth of |r−b| is the base conceivable. Note that the number x and the numbers shaped by digits of each tone, may contain driving zeros. Input :The principal line contains one integer t (1≤t≤10) — the number of experiments. Then, at that point, t experiments follow. Each experiment comprises of two lines. The main line contains three integers n, A, B (2≤n≤40, 1≤A,B≤40).…Let A = {a, b, c} and B = {u, v}. Write a. A × B b. B × AWrite a function which takes two integer parameters for values to be added together and returns the result by value. The function may not print anything or read anything directly from the user (i.e. no cin/cout in the function). Assume that the values passed to the function will not be negative, but could be 0 or positive, and will both be integers. The function must implement addition recursively, and cannot use the standalone + operator (only ++) or call any other functions.
- code for this in C: Write a program that reads two matrices of integers. It then generates the sum and difference of the two matrices. The sum of the two matrices of the same size is a matrix with elements that are the sums of the corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes. If A and B are matrices of the same size, then we define subtraction as follows: A – B = A + (-B). Thus, to subtract matrix B from matrix A, we simply subtract corresponding elements.8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.Write recursive functions for the following equations:a. Harmonic number is defined by the equationb. Fibonacci numbers are defined by the formula:FN = FN-2 + FN-1, for N ≥ 2 with F0 = 0 and F1 = 1
