Solved in 3 steps
- (Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.Shift Right k Cells (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as: [ 0,0,0,10,20,30 ]Exercise 1: //The max function the max between a and b, it returns a if a == //b public double max(double a, double b); //The mult function returns the result of a * b public double mult(double a, double b); //The exist in array function returns the index of the element //‘a’ if //‘a’ exist in array ‘arr’ otherwise returns ‘-1’ public int existsInArray(int [] arr, int a); //Are array equals method compares two arrays and returns true // if the elements of array ‘a’ are equal to elements of array // ‘b’, element by element. If equals it returns 0, it returns - // 1 if not public int areArrayEquals(int [] a, int [] b); Devise four executable test cases for every method in the JUnit notation. See the attached handout for a refresher on the notation.
- Rotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30](Maximum element in an array) Implement the following method that returns the maximum element in an array . public static > E max (E[] list) Write a test program that prompts the user to enter 10 integers, invokes this method to find the max.1. Code a method that will read in values from the user. 2. Add the following: Allow the user to enter any number of positive integers Store them in an array or array list Let the user enter -1 to end their list of values. Add error checking to make sure they enter positive values or a -1.
- Write a class with name Arrays . This class has an array which should be initialized by user.Write a method Sum that should sum even numbers in array and return sum. write a function with name numFind in this class with working logic as to find the mid number of an array. After finding this number calculate its factorial.Write function that should display sum and factorial.Don’t use divide operatorReverse ArrayWrite a function that accepts an int array and the array’s size as arguments. The function should create a copy of the array, except that the element values should be reversedin the copy. The function should return a pointer to the new array. Demonstrate thefunction in a complete program.class Main { // this function will return the number elements in the given range public static int getCountInRange(int[] array, int lower, int upper) { int count = 0; // to count the numbers // this loop will count the numbers in the range for (int i = 0; i < array.length; i++) { // if element is in the range if (array[i] >= lower && array[i] <= upper) count++; } return count; } public static void main(String[] args) { // array int array[] = {1,2,3,4,5,6,7,8,9,0}; // ower and upper range int lower = 1, upper = 9; // throwing an exception…
- 1. Create a program that will accept 10 array values from the user and determined the maximum and minimum value for that array set.2. Create a program that will find duplicate values of an array integer3. Create a program to find the third smallest element in an array. -USED JAVA PROGRAMMING LANGUAGEIn C Programming Language Palindrome: “A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward, such as ‘madam’ or ‘kayak’” (excerpt from Wikipedia).Write a program that reads 8 words from Palindrome.txt and checks whether the word you read is a palindrome (please read its description above) or not. Print the index numbers of all the palindrome words in your array. You are required to read words character by character into a character array.• Write readFile function, which gets a file pointer and a two-dim array, to read each word(bunch of characters) line by line and store them into a two-dim character array.• Write findSize function takes a one-dim array and returns its actual size.• Write isPalindrome function takes a one-dim character array to check whether the content is a polindrome or not. If the word (character squence) is a palindrome, then it returns 1. Otherwise, it returns 0.Correctly define a method that takes and returns arrays。Create initialized and allocated arrays and array variables。Write procedures(void methods)that modify array parameters。Process arrays using selection statements and / or the logical operators。。Process arrays with loops。Use counting,accumulation,extreme value,and linear search algorithms
