Need python help. For problems 1 and 2, add your code to the file Lab2.java. Add your tests in the main function of Lab2.java. Do not use static variables in class Lab2 to implement recursive methods. Problem 1: Implement a recursive method min that accepts an array and returns the minimum element in the array. The recursive step should divide the array into two halves and find the minimum in each half. The program should run in O(n) time and consume O(logn) memory. Demonstrate the output of min on the array int [] a = { 2, 3, 5, 7, 11, 13, 17, 19, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 23, 29, 31, 37, 41, 43 } Problem 2 You have been offered a job that pays as follows: On the first day, you are paid 1 cent, on the second day, 2 cents, on the third day, 4 cents and so on. In other words, your pay doubles every day. Write a recursive method computePay that for a given day number computes the pay in cents. Assume that you accumulate all the money that you are paid.

3D Array: Use python to solve this problem. We already know how to operate 2D arrays. Now we have to use 3D arrays in order to construct LCS with 3 parameters. Multidimensional array means multiple arrays of different dimensions or sizes can be held by a single array. We will learn about 3D arrays with an example. Suppose we want to store midterm and final marks separately of four different courses of three students in a single array. We can easily do it by using a 3D array. Python: for i in range(len(A)): print("Student: ",(i+1)) for j in range(len(A[i])): print("Course: ",(j+1)) print("Marks of Mid and Final: ") for k in range(len(A[i][j])): print(A[i][j][k],end=" ") print() print() OUTPUT: Student: 1 Course: 1 Marks of Mid and Final: 30 25 Course: 2 Marks of Mid and Final: 35 40 Course: 3 Marks of Mid and Final: 41 45 Course: 4 Marks of Mid and Final: 26 26 Student: 2 Course: 1 Marks of Mid and Final: 41 45…
pls give mommens by expression and statements , thanks Recall that in C++, there is no check on an array index out of bounds. However, during program execution, and array index out of bounds can cause serious problems. Also, in C++, the array index starts at zero. Design and implement the class myArray that solves the array index out of bounds problem, and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements: myArray<int> list(5); //Line 1 myArray<int> myList(2, 13); //Line 2 myArray<int> yourList(-5, 9); //Line 3 This statement in line one declares list to be an array of five components, the component type is int, and components are: list[0], list[1],…, list[4];…
code required for python: For this question, you will be required to use the binary search to find the root of some function f(x)f(x) on the domain x∈[a,b]x∈[a,b] by continuously bisecting the domain. In our case, the root of the function can be defined as the x-values where the function will return 0, i.e. f(x)=0f(x)=0 For example, for the function: f(x)=sin2(x)x2−2f(x)=sin2(x)x2−2 on the domain [0,2][0,2], the root can be found at x≈1.43x≈1.43 Constraints Stopping criteria: ∣∣f(root)∣∣<0.0001|f(root)|<0.0001 or you reach a maximum of 1000 iterations. Round your answer to two decimal places. Function specifications Argument(s): f (function) →→ mathematical expression in the form of a lambda function. domain (tuple) →→ the domain of the function given a set of two integers. MAX (int) →→ the maximum number of iterations that will be performed by the function. Return: root (float) →→ return the root (rounded to two decimals) of the given function. my code below , however as…
use c++ by Using dynamic arrays, implement a polynomial class with polynomial addition,subtraction, and multiplication. Discussion: A variable in a polynomial does nothing but act as a placeholder forthe coefficients. Hence, the only interesting thing about polynomials is the arrayof coefficients and the corresponding exponent. Think about the polynomialx*x*x + x + 1Where is the term in x*x ? One simple way to implement the polynomial class is touse an array of doubles to store the coefficients. The index of the array is theexponent of the corresponding term. If a term is missing, then it simply has a zerocoefficient.There are techniques for representing polynomials of high degree with many missingterms. These use so-called sparse matrix techniques. Unless you already knowthese techniques, or learn very quickly, do not use these techniques.Provide a default constructor, a copy constructor, and a parameterized constructorthat enables an arbitrary polynomial to be constructed.Supply an…

IN C++ You have given an array aa of length n and an integer x to a brand new robot. What the robot does is the following: it iterates over the elements of the array, let the current element be q. If q is divisible by x, the robot adds x copies of the integer q/x to the end of the array, and moves on to the next element. Note that the newly added elements could be processed by the robot later. Otherwise, if q is not divisible by x, the robot shuts down. Please determine the sum of all values of the array at the end of the process. Input The first input line contains a single integer tt (lâ%oatâ%o¤100) â€" the number of test cases. The first line of each test case contains two integers n and x (1â%o¤nâ%o010^5, 2â%oaxâ%o ¤10^9) â€" the length of the array and the value which is used by the robot. The next line contains integers al, a2, .., an (lâ%o¤aiâ%o¤1O^9) â€" the initial values in the array. It is guaranteed that the sum of valuesn over all test cases does not exceed 10^5 Output For…

Develop python program of function randomArray(m, n) that takes two integers as argument and returns a 2D m-by-n array with random elements in it. Develop python program of function adder(a1, a2) that reads two 2D arrays of the same size and returns an array that is the summation of a1 and a2. To add the two arrays, you need to add their elements, correspondingly. Develop a python program of function inverseArray(a) that takes a 2D-array as argument and inverses the array. You will need to inverse the rows, first and then inverse the columns, next. For instance, if the array = [[2, 3, 4], [5, 6, 7]], the inverse will be = [[7, 6, 5], [4, 3, 2]]
Please written by computer source Question 1: Suppose we wish to write a procedure that computes the inner product of two vectors u and v. An abstract version of the function has a CPE of 14–18 with x86- 64 for different types of integer and floating-point data. By doing the same sort of transformations we did to transform the abstract program combine1 into the more efficient combine4, we get the following code: Our measurements show that this function has CPEs of 1.50 for integer data and 3.00 for floating-point data. For data type double, the x86-64 assembly code for the inner loop is as follows: Assume that the functional units have the characteristics listed in Figure 5.12. **See last page for figures A.
