Please write a function named count_matching_elements (my_matrix: list, element: int), which takes a two-dimensional array of integers and a single integer value as its arguments. The function then counts how many elements within the matrix match the argument value. An example of how the function should work: m = [[1, 2, 1], [0, 3, 4], [1, 0, 0]] print (count_matching_elements (m, 1)) 3 Sample output

- You need to generate a (5x12) rain matrix (Rain[5][12]) that contains the average rainfall over 12 months for a 5 year period. You program should do the following steps: Create a 5x12 integer rainfall matrix Create a 5 element array of int pointers(int * Rain[5]) and assign each pointer to the address of the first element of each row Populate the elements of the matrix with pseudo-random numbers having a range from 0-100 Use the rand( ) function to generate your temperatures. The output of rand() should be mod with 100 (rand()%100) in order to get reasonable rainfall values. Init the random number generator with long seed = srand(67) This task should be performed by a function, void RainGen(int* Rain[ ], int R, int C), that populates all the matrix entries. After generating all rainfall matrix entries, print the entire matrix using the function, void Print(int* Rain[ ], int R, int C); Calculate the total monthly Rainfall per year for the entire five years. Use the following…def create_identity_matrix(n):"""Create a nxn sized identity matrix.

Assume that the column size is fixed at 4. If no sum is odd, return -1.
- matrixA = [[1, 2], [3, 4], [5, 6]] where the number of first-level elements represent the number of rows and the number of second-level elements represent the number of columns. Write a function create_matrix that takes a sequence of integers and two additional numbers that specify the shape of the matrix (i.e., the number of rows and columns, respectively) to create a nested list representing the matrix filled by these integers row-wise. For example, calling create_matrix(*range(4, 19), rows=3, cols=5) returns a nested list representing the following 3 (rows) by 5 (columns) matrix: 4. 7 8. 9 10 11 12 13 14 15 16 17 18 Also include exception handling so that the function prints an error message if the number of intergers does not match the product of the number of rows and that of columns. For example, calling create_matrix(2, 3, 14, 15, rows=3, cols=2) prints The number of elememnts does not match the shape of the matrix. In [e]: # Write your function definition below matrixA = [[1,…Write a function that displays an n-by-n matrix using the following header: void printMatrix(int n)Each element is 0 or 1, which is generated randomly. Write a test program that prompts the user to enter n and displays an n-by-n matrix.PHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .
- c coding saw this in an intro to c text book, need help In this question you will write a function row_sums that accepts an n × m matrix and computes the sum of each of its rows and stores that data in an array. For example, the sums of the rows of the matrix 1 2 3 4 5 6 7 8 9 are [6, 15, 24]. The function will have four arguments: integers n and m corresponding to the dimensions of the matrix, matrix corresponding to the matrix data, and sums which will be an array where you store the row sums. You can assume that n and m are positive integers at most 10. Your function must have the following prototype: void row_sums(int n, int m, int matrix [][10] , int sums []); For consistency the argument matrix will always have 10 columns, but you must ignore all columns with indices greater than or equal to m or rows with indices greater than or equal to n. Demonstrate your function by initializing an example matrix in main, calling your row_sums function on that matrix, and then printing…In cell C18 type a VLOOKUP function to find the corresponding letter grade (from column D) for the name in A18. The table array parameter is the same as in B18. Type FALSE for the range lookup parameter. Copy the formula in C18 to C19:C22Notice this formula works correctly for all cells. Range lookup of FALSE means do an exact match on the lookup value whether or not the table array is sorted by its first column. In cell E11, type an IF function that compares the score in B11 with the minimum score to pass in A5. If the comparison value is true, display Pass. Otherwise, display Fail. Copy the formula in E11 to E12:E15. Did you use appropriate absolute and relative references so the formula copied properly? In cell F11, type an IF function that compares the grade in D11 with the letter F (type F). If these two are not equal, display Pass. Otherwise, display Fail. Copy the formula in F11 to F12:F15in this javascript function ,how tochange the code to sort the array elements in descending order function get_odd_num(){ var max_val= 1000; var randNum= Math.random()*max_val; if(randNum %2 == 0){ if(randNum == max_val){ randNum = randNum -1 ; }else{ randNum = randNum +1 ; } }} function sortArray() { var array =[]; for (var i = 0; i < 10; i++) { array.push(get_odd_num()); } var temp = 0; for (var i = 0; i < array.length; i++) { for (var j = i; j < array.length; j++) { if (array[j] > array[i]) { temp = array[j]; array[j] = array[i]; array[i] = temp; } } } return array;} console.log(sortArray());
