- Create a function using Java: Number of Rows = 3-6 Number of Columns = 3-6 Function Name: winInDiagonalFSParameters: board: 2D integer array, piece: integerReturn: booleanAssume board is valid 2D int array, piece is X==1/O==2.Look at all forward slash / diagonals in the board. If any forward slash / diagonals has at least 3consecutive entries with given type of piece (X/O) (3 in a row XXX, OOO), then return true,otherwise falsearrow_forwardNow, write another function that prints the values of any array in reverse order. (The function should not change the original array). As an example, if a [] = {1, 2, 3, 4, 5}; The function would print the values in reverse as: 5, 4, 3, 2, 1arrow_forwardCreate a function named "onlyOdd".The function should accept a parameter named "numberArray".Use the higher order function filter() to create a new array that only containsthe odd numbers. Return the new array.// Use this array to test your function:const testingArray = [1, 2, 4, 17, 19, 20, 21];arrow_forward
- 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()arrow_forwardDefine a function named "getExamListInfo" that accepts an array of Exam objects and its size. It will return the following information to the caller: - The number of exams with perfect score - The number of exams with "Pass" status - The index of the Exam object in the array that has the largest score. For example, if you get the exam info for this array of Exam object Exam examList[] = { {"Midterm1 Exam", 90}, {"Midterm2 Exam", 80}, {"Final Exam", 50}, {"Extra Credit", 100}, {"Initial Test", 0}, {"Homework1", 69} } ; You will get Perfect Count: 1 Pass Count: 3 Index of the largest: 3 C++arrow_forwardDefine the following function that takes an array of integers to fill it with randomly created integers between the given range. The second argument of the function is the size of the array, "first" is the first value for random integers and "nums" is the number of terms in the given range. (i.e., when first is 10 and nums 35, the range will be between [10-44]) The function also returns the minimum value in this array. int myRandArr(int arr[], int size, int first, int nums); Write the main function to create an array and test your function. For this purpose, create and integer array between the range [-15-15] and display values together with the minimum value. Sample Output: Elements of randomly created array: 4 13 -11 -12 -2 The min of those values: -12arrow_forward
- You are designing a function that will manipulate an array of integers. It needs to work for arrays of any length. What is the minimum number of parameters your function will have?arrow_forwardQuestion 1. Write a console application with several functions that deal with a two-dimensional array of positive integers: The number of rows and number of columns of the array should be 20. Fill the array with random numbers between 1 and 1000. Search for the prime numbers in the array using the following function in your code: bool isPrime(int n) for (int i = 2; iarrow_forward4. Arrays. In order to test the functions in this question, you will need an array. We can create a three- dimensional test array as follows: testArray xijk - máx rij,k i=1 i=1 i=1 (b) Now suppose we want a function testFn2 which returns the d2 x d3 matrix {zj.k} where di Zj,k = Σ i=1arrow_forwardWrite the body of a void function whose header is indicated below, and which prints each of the numbers in an array, which are divisible by 5 as well as how many numbers are divisible by 5. The function accepts the array x, and the number of elements (size), in the array as parameters. void divisibleBy5 (int x[ ], int size )arrow_forwardWrite a maxConsecutiveDiff function which returns the maximum difference between any two consecutive values in the array.Consecutive values are next to each other in an array (+/- 1 index)This function should accept all required data as parameters.ExamplesIf the array is 17 15 16 11 14 the maximum consecutive difference is 5 which is the difference between 16 and 11.If the array is 10 13 11 12 19 the maximum consecutive difference is 7 which is the difference between 12 and 19.arrow_forwardarrow_back_iosarrow_forward_ios
