Question
- Develop python program of function random array(m, n) that takes two integers as an 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 summarizes a1 and a2. To add the two arrays, you need to add their elements correspondingly.
- Develop a python program of function inverse ray(a) that takes a 2D-array as an 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]]

- Given a vector of real numbers r = (r1, V2, ..., rn). We can standardize the vector using the formulation: V; = "im, where m is the ri-m mean of the vector r, and s is the standard deviation of r. The vector v = (V1, V2, . , Un) will be the scaled vector. ... 9 Write a Python function scale_vec(r) that takes the vector r as input and returns the scaled vector v. Sample inputs and outputs: • Input: np.array([1, 3, 5]), output: [-1.22474487 0. 1.22474487] Input: np.array([3.3, 1.2, -2.7, −0.6]), output: [1.35457092 0.40637128 -1.35457092 -0.40637128] Hint: Use numpy.mean and numpy.std with default parameters. [ ] # Write your function here Let's test your function.

- language: Python Problem: Define a global variable, countcalls, and increment it inside a power(x, n) function, so that it counts the number of times the power function is called. Show that it produces the expected number of calls for power(2, 10) and power(5, 10) and power(5, 0), each separately.arrow_forwardSolution for: Pythonarrow_forwardCreate a python code LIFE OF A BOUNCER A line of teenagers is trying to go to a never-ending party but you as a bouncer cannot permit to enter those below 18 years old. Input: Length of the line of teenagers An array which holds the age of the teenagers Process: If the age of the teenager at the front of the line is above or equal to 18, let him/her go to the party and remove him/her from the line. Then go to the next person. If the age of the teenager at the front of the line is below 18, make him move to the end of the line and add 1 year to its age. Then go to the next person. Once everyone was assessed, repeat the process to those that was sent back to the end of the line until everyone got in. Output: Display each year’s line Example: Input start year: 2021 Input length: 5 Input array: 17 18 19 16 20 Year 0: 17 18 19 16 20 Year 1: 18 17 Year 2: 18arrow_forward
