PYTHON Given an array consisting of N integers returns the maximum sum of two numbers who’s digits add up to an equal sum. If there are no two numbers who’s digital shave an equal sum, the function should return -1  write an efficient algorithm of the following assumption: N is an integer within the range [1..200.000]

Write a function that inputs N (assume N<30), and N integers into a 1-Dimensional array. Itwill find and display how many times the array elements are repeated in the array.Sample Run:Enter N (N<30): 6Enter 6 integers: 1 2 1 1 7 71 occurs 3 times2 occurs 1 times7 occurs 2 times

Prompt: In python langauge, write a function that adds a random noise to all elements of a NumPy array Code:  import numpy as np import math import matplotlib.pyplot as plt import pandas as pd   def addNoise(inputArray):   modifiedArray = np.zeros(len(inputArray))   #YOUR CODE HERE:   return(modifiedArray) def test(): inputs = np.arange(-5, 5,0.2) outputs = addNoise(inputs) plt.figure(1) plt.plot(inputs) plt.title('Input') plt.xlabel('Index') plt.ylabel('Value') plt.show() plt.figure(2) plt.plot(outputs, 'black') plt.title('Output') plt.xlabel('Index') plt.ylabel('Value') plt.show() test()

The perimeter P of the rectangle bounded by the two sides L and Wis P=2(L + W) Write a piece of code that implements this equation. In other words, translate the above equation into code. This should be a simple one-liner! Do not use the np.random.normal() function. You must use the previously defined arrays L and w. Python performs calculations on arrays element-by-element. ▼ #Taking input for the lengths and widths as arrays lengths [] widths [] num_rectangles int(input ("Enter the number of rectangles: ")) for i in range(num_rectangles): length width = float (input (f"Enter the length of rectangle {i + 1}: ")) float (input(f"Enter the width of rectangle {i + 1}: ")) lengths.append(length) widths.append(width) = # Calculating the perimeters for each rectangle perimeters [2* (LW) for L, W in zip(lengths, widths)] #Printing the results for i, P in enumerate (perimeters): print (f"The perimeter of rectangle {i + 1} is:", P) #Let's see the perimeter: print ("perimeter: ", P) This…
