Write a function called unroll, which takes in a square array of arrays (i.e. a grid with n rows and n columns). An input could look like this: constsquare=[[1,2,3,4],[5,6,7,8],[9,10,11,12],[13,14,15,16]]; unroll should take in such a square array and return a single array containing the values in the square. You should obtain the values by traversing the square in a spiral: from the top-left corner, move all the way to the right, then all the way down, then all the way to the left, then all the way up, and repeat. For the above example, unroll should return [1, 2, 3, 4, 8, 12, 16, 15, 14, 13, 9, 5, 6, 7, 11, 10].

Prompt: In Python language, write a function that applies the logistic sigmoid function to all elements of a NumPy array. Code:   import numpy as np import math import matplotlib.pyplot as plt import pandas as pd   def sigmoid(inputArray):               modifiedArray = np.zeros(len(inputArray))               #YOUR CODE HERE:               return(modifiedArray) def test(): inputs = np.arange(-100, 100, 0.5) outputs = sigmoid(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()

Imagine that you are a biomedical engineer analyzing DNA sequences. You have numerical measurements from two different measurement sources, m1 and m2, both of which are arrays. Write a function named dna that takes these two arrays as inputs. It should return a character array string of nucleotides (represented by the letters A, C, G and T). For a given index, i, the nucleotide in the string is: - ‘A’ if m1(i) >= 0 and m2(i) >= 0 - ‘C’ if m1(i) < 0 and m2(i) >= 0 - ‘G’ if m1(i) >= 0 and m2(i) < 0 - ‘T’ if m1(i) < 0 and m2(i) < 0    code to call the function  m1 = [-2 -3 2.5 0.3]; m2 = [1.1 2.1 -0.8 0.1]; sequecne = dna(m1,m2);  function dna    Please use MATLAB

Create a function using Java: Number of Rows = 3-6 Number of Columns = 3-6   Function Name: winInDiagonalBSParameters: board: 2D integer array, piece: integerReturn: booleanAssume board is valid 2D int array, piece is X==1/O==2.Look at all backward slash \ diagonal in the board. If any backward slash \ diagonal has atleast 3 consecutive entries with a given type of piece (X/O) (3 in a row XXX, OOO), then return true,otherwise false.

Write a function that verifies if a given number exists in an array of floats. The function is supposed to return the first position in where the number is encountered. If the given number does not exist, the function returns –1. Then write a complete program that asks the user to enter an array of 8 floats and calls the function. The prototype of the function should be like:   int Search (floats a[ ], int n, float number);   Example: Consider the following array of floats int x[8]={2.1, 5.0, 9.8, 4.4, 6.8, 12.88, 9.87, 4.56}; If the number to be searched is 5.4, the function returns  –1 If the number to be searched is 9.8,the function returns  2   C++ language only.

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below.             The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std;   // Global constants const int ROWS = 3;  // The number of rows in the array const int COLS = 3;  // The number of columns in the array const int MIN = 1;  // The value of the smallest number const int MAX = 9;  // The value of the largest number //…

Write a program that uses a function named NameSlice to "slice" the last name off of a string that contains the user's first and last names. This function accepts a character array as its argument. It scans the array looking for a space. When it finds one, it replaces it with a null character. Enter your first and last names, separated by a space: Aicha BeyaFar Your first name is: Alcha Press any key to continue
