For each of the following problems, you should write your answer as an expression. You do not need togive the final numeric value. For example, if your answer is the number of 6-permutations of a set with 10elements, you should write P(10,6) or 10!/4! or 10 x 9 x 8 x 7 x 6 x 5, but not 151200.How many ways are there to choose 6 items from 10 distinct items if...a ... the order of the items matters and repetition of items is not allowed?b... the order of the items matters and repetition of items is allowed?C...the order of the items does not matter and repetition of items is not allowed?d... the order of the items does not matter and repetition of items is allowed?

Nationality. Prove the function works by testing it 2. BLACKJACK: Sample two cards from a "deck of cards" (ace, 2-10, jack, queen, king). Find the total of the two cards (ace counts as 11 and facecards count as 10). If the total is 21 print "BLACKJACK!" otherwise print "Try again". Keep drawing pairs of two cards until you get blackjack. Set your seed to 30 at the start of this problem ? Write 2 that ohe to frame for NAe If NA is found it should replace NA with the

Write the value_equality method.Given the two expressions ? and ?, first compute the set of variables ? that appear in either ? or ?. Then, the idea consists in performing num_sample times the following test for equality: First, produce a variable assignment (a dictionary) mapping each variable in ? to a random value. Choose these random values from the gaussian distribution centered around 0 and with standard deviation 10 (for instance; any continuous distribution with infinite domain would work). You can obtain such numbers using random.gauss(0, 10). Then, compute the values of ? and ? with respect to that variable evaluation. If the values are closer than a specified tolerance tolerance, you consider ? and ? equal (for that variable valuation). Otherwise, you can stop and return that ? and ? are different. If you can repeat the process num_sample times, and ? and ? are considered equal every time, then you declare them equal. WRITE CODE IN PYTHON
Instrument FrequencyCounter to use Stopwatch and StdDraw to make a plot where the x-axis is the number of calls on get() or put() and the y-axis is the total running time, with a point plotted of the cumulative time after each call. Run your program for Tale of Two Cities using SequentialSearchST and again using BinarySearchST and discuss the results. Note : Sharp jumps in the curve may be explained by caching, which is beyond the scope of this question.
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.
in Python Minima in permutations. Write a program that takes an integer n from the command line, generates a random permutation, prints the permutation, and prints the number of left-to-right minima in the permutation (the number of times an element is the smallest seen so far). Then write a program that takes integers m and n from the command line, generates m random permutations of length n, and prints the average number of left-to-right minima in the permutations generated

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…
Modify the algorithm described in the class to calculate the longest palindrome, such that there is enough information on the table to build the longest palindrome from the table. Hint: You can use similar data structure used for Longest common subsequence. Explain how you can rebuild a longest palindrome from the given string using this data structure.
