Exercise A: "Matrix Validity Test" For this exercise you will design and implement a function that takes one argument and returns single Boolean value indicating whether or not the argument is a "valid" matrix. The operation definition for a "valid" matrix (for this activity) is a rectangular list of lists of numeric data element so your function will need to test each of these three properties separately. In order to complete this task, you will need to: recognize that the two data types in Python that are actually numerire "int" and "float" read about Python's built-in "isinstance" function

4. Write a function named “removeNegativePrice” that accepts the vector of pointers to PurchaseOrder objects. It will go through that list and remove all PurchaseOrder objects with the negative cost per item. It will also return how many PurchaseOrderobjects that it has removed from the list. Please show how this function is being called and can delete PurchaseOrder objects with negative cost from the list. C++
OCAML programming (Lights Out) The mechanics described in this exercise can be used to implement a game lights out. 1. Create a function flip val flip : bool array array -> int -> int -> bool array array = <fun> that given a bool matrix and two integers i; j. it negates the values(true!false, false!true) at location i; j in the matrix, as well negatingthe values on the (up to) 4 horizontally/vertically adjacent elements. 2. Create a function print matrix val print_matrix : bool array array -> unit = <fun> that given a bool matrix, it prints it on screen (true !"T", false!"F"). Sample input: # let matrix= [|[|false; true; true; false|]; [|true; false; false; true|];[|false; false; true; true|]|];;# print_matrix matrix;;FTTFTFFTFFTT# flip matrix 1 4;;# print_matrix matrix;;FTFTTFFFFFTT
Write the function definition for a value returning function that receives an array of integer values, the array length, and an integer target value as parameters. The function should perform a li ear (sequencial) search for the target value. If the value is found, the function should return the index position of the target value, otherwise, it should return -1. Write only the function definition.
When a sentence is entered, write the most relevant C code in that sentence. You should not write the following 3 rules without changing them. void maxinChar(char sentence[], size: in the given string and at most in the picture string) it is underdrawn. Within this function keep its escapes defense of a character in an array. By parameterizing this array to the findMinIndex and findMaxIndex functions, the set value is returned for the minimum and transition elements in this array. In the sentence given according to the returned values, you talk less and mostly about yourself. int findIndex[] is the smallest element in a given array of integers. The array int findx(Index] overnights inside the largest element in an array of integers given you. -------- Meaning: Enter a sentence: Hello world, welcome to the java programming lesson Max Character: o Minimum Character: j
Language: JAVA Script write a function 'keyValueDuplicates (obj) that takes an object as an argument and returns an array containing all keys that are also values in that object. Examples: obj1 = { orange: "juice", apple: "sauce", sauce: "pan" }; console.log(keyValueDuplicates (obj1)); // ["sauce"] obj2 = { big: "foot", foot: "ball", ball: "boy", boy: "scout"};console.log(keyValueDuplicates(obj2)); // ["foot", "ball", "boy"] obj3 = { pizza: "pie", apple: "pie" pumpkin: "pie"); console.log(keyValueDuplicates (obj3)); // [] *******************************************************************/function keyValueDuplicates (obj) { | // Your code here } /*****DO NOT MODIFY ANYTHING UNDER THIS LINE*********/ try { | module.exports = keyValueDuplicates; } catch (e) { | module.exports = null;}
Write a findSpelling Function -PHP Write a function findSpellings($word, $allWords) that takes a string and an array of dictionary words as parameters. The function should return an array of possible spellings for a misspelled $word. One way to approach this is to use the soundex() Words that have the same soundex are spelled similarly. Return an array of words from $allWords that match the soundex for $word. I have most of the code. How do I append the $sound to the $mathcing array?
PHP Write a modeMaker function Write a function modeMaker() that forms a closure such that the function it returns can be used with your reduce() function above to find the mode of an array. The mode of an array is the value that appears the most frequently (so in the $arr above, the mode is 5). To do this, you will need an array called $seen that keeps the count of times an element has been examined At the end of the reduce function, the $seen array should look like the following for the $arr above: Array ( [10] => 1 [5] => 3 [3] => 1 [1] => 1 [2] => 1 [7] => 1 ) Note that the closure you generate should always be returning the current mode for what it has seen so far (so it will either be the current mode, or the new element passed in). The following is a start for modeMaker: function modeMaker() { $seen = array(); return function($current, $new) use (&$seen) { // your code that uses $seen goes here }; } $mode =…
Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks
Ocaml programming 1. Create a type slidingTile, consisting of a char matrix and two integers xand y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = <fun> that given a slidingTile and two integers, that represent a location in thematrix, it slides the tile from the specied location to the empty tile, thenreturns the altered slidingTile. If provided location is not adjacent to theempty tile, or out of bounds, then return the slidingTile unaltered. 3. Create a function val print_tile : slidingTile -> unit = <fun> that prints a slidingTile on screen with the corresponding characters fromthe matrix. However, print an empty space where the empty tile is instead.
C++ For this week’s assignment, you’ll be making a function that can multiply not only two matrices, but also a single matrix and a scalar. To build a matrix in C++, you’ll need to familiarize yourself with multi-dimensional arrays. These are the same as regular arrays, but when you initially define them, instead of saying:Int dataArray[10];You’d say:Int dataArray[10][10];This will create an array of 100 objects, that you can think of in a 10 x 10 grid. It should be noted that it’s actually the same as saying ‘int dataArray[100]’, and can be used in the same way.You can also initialize two-dimensional arrays like this:Int matrix[2][3] = {{ 0, 1, 2} ,{3, 4, 5}};Or like this:Int matrix[2][3] = {0,1,2,3,4,5};One of them’s just slightly easier to recognize as a two dimensional array than the other. Now while THIS project is only dealing with 2x2 matrices, it will be to your benefit if you plan your program to be able to handle matrices of any size...Your function will need to correctly…
please solve it in C : Write a function called search that takes an array of Books structures and a string called title i.e. the header of the function will be: void search(struct Books b[], char title[]). This function finds the book in the array b[] whose title is the same as the parameter called title and then prints all the info (title, authors, id, subject) of that book
