For each of the following problems, you should write your answer as an expression. Do notgive the final numeric value. For example, if your answer is the number of6-permutations of a set with 10 elements, you should write P(10,6) or 10!/4! or 10 × 9 × 8 ×7 × 6 × 5, but not 151200. (25 pt., 5 pt. each) A French pastry shop sells 15 different flavors of macarons. Assumethat it has an unlimited supply of each type. How many ways are there to choose 12macarons from these 15 flavors if...3.1...they are all the same flavor?3.2 ...they are all different flavors?3.3 ...half are one flavor and half are a different flavor (for example, half are raspberry andhalf are chocolate)?3.4...at most 4 are salted caramel?3.5 ...at least 2 are pistachio and at least 4 are hazelnut?

3.1 The number of ways to choose 12 macarons from 15 flavors if they are all the same flavor is:This…

Write a section of code that creates the pairings for two sets of numbers a = {0 – 5} and b = {9 - 15}. Each number must be paired with all numbers from the other set. This is a cross product, denoted as a x b. That is, for every number in a, it should be listed with every number in b, such as (0, 9), … (0, 15), and so on. Make sure there are no spaces between numbers and the (, ), or comma.
Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() { const int NUM_VALS = 4; int courseGrades[NUM_VALS]; int i; for (i = 0; i < NUM_VALS; ++i) { cin >> courseGrades[i]; } /* Your solution goes…

Computer Science This is a codingbat problem. Please answer in Java and do not change the starter code. You have been asked to write the game of tic tac toe. In the first version of the game, we will only be comparing horizontally for a win. A win is determine by all of the elements in a row either being an X or an O. You need to return a String with the winner or TIE if there is no winner. ticTacToe(["X", "O", "O"], ["X", "O", "O"], ["X", "X", "X"]) → "X"ticTacToe(["X", "O", "X"], ["X", "X", "O"], ["O", "O", "O"]) → "O"ticTacToe(["X", "O", "X"], ["X", "X", "O"], ["O", "X", "O"]) → "TIE" public String ticTacToe(String[] top, String[] middle, String[] bottom) { }

Write method to reverse sequence of elements in array. if you call a method with array: 1 4 9 16 9 7 4 9 11 array is converted to. this is just example 11 9 4 7 9 16 9 4 1
In the "Common Array Algorithms" section, you learned how to find the position of an element in an array. Suppose you want to find the position of the second match. You could remove the first match and start over, but that would be wasteful. Instead, adapt the algorithm from that section so that it starts the search at a given position, not zero. Complete the following code.
Using JavaScriptDefine a function getMonth which accepts number from 1 to 12 as an argument and return the descriptive name of the month. For example: getMonth(1) should return January while getMonth(12) returns December, finally getMonth(-1) returns null. Use array or object to define a list of names for the month and refrain from using if statement to check the argument if it's 1, 2, etc.
