Q2: Secret Courses Dan's recently announced that he's teaching n top-secret courses next semester. Instead of enrolling in them through ACORN, students need to email Dan to express their interests. These courses are numbered from 1 to n in some arbitrary order. In particular, if a student named s is interested in taking a course c, they need to send an email to Dan containing the message c s. Note that if a student is interested in taking multiple courses, they need to send multiple emails, one per course. Upon receiving a message c s, Dan looks at the list of students already enrolled in course c. If there's already a student on the list whose name is too similar to s, Dan assumes s is the same student and ignores the message. Otherwise, he enrolls s in the course. Dan considers two names too similar if and only if they have the same length and differ in at most one letter (note that "a" and "A" are considered the same letter). For example, "Josh" and "Josh" are too similar. "Sam" and…

Credit card numbers follow certain patterns: It must have between 13 and 16 digits, and the number must start with:■ 4 for Visa cards■ 5 for MasterCard credit cards■ 37 for American Express cards■ 6 for Discover cards In 1954, Hans Luhn of IBM proposed an algorithm for validating credit card numbers. The algorithm is useful to determine whether a card number is entered correctly or whether a credit card is scanned correctly by a scanner. Credit card numbers are generated following this validity check, commonly known as the Luhn check or the Mod 10 check, which can be described as follows (for illustration, consider the card number 4388576018402626): 1. Double every second digit from right to left. If doubling of a digit results in a two-digit number, add up the two digits to get a single-digit number. 2. Now add all single-digit numbers from Step 1. 3. Add all digits in the odd places from right to left in the card number. 4. Sum the results from Steps 2 and 3. 5. If the result from…

Compare Numbers -  Python Language please! Programming challenge description: Little Tommy is in kindergarten on the first day of class. His teacher has taught him about inequalities today, and he is learning how to draw crocodiles to represent them. When there are two numbers, A and B, there are three options:1. If A is greater than B, then draw '>'. The crocodile's mouth is pointed toward the bigger number, A.2. If A is less than B, then draw '<'. The crocodile faces B.3. If A is equal to B, draw '='. The crocodile is confused and keeps its mouth shut.Unfortunately, Tommy does not like to do his homework, and has bribed you to write a program to do it for him.

Brute force equation solver this is python program. Numerous engineering and scientific applications require finding solutions to a set of equations. Ex: 8x + 7y = 38 and 3x - 5y = -1 have a solution x = 3, y = 2. Given integer coefficients of two linear equations with variables x and y, use brute force to find an integer solution for x and y in the range -10 to 10. Ex: If the input is: 8 7 38 3 -5 -1 Then the output is: 3 2 Use this brute force approach: For every value of x from -10 to 10 For every value of y from -10 to 10 Check if the current x and y satisfy both equations. If so, output the solution, and finish. Ex: If no solution is found, output: No solution You can assume the two equations have no more than one solution. Note: Elegant mathematical techniques exist to solve such linear equations. However, for other kinds of equations or situations, brute force can be handy.

Nearest polygonal number def nearest_polygonal_number(n, s): Any positive integer s > 2 defines an infinite sequence of s-gonal numbers whose i:th element is given by the formula ((s-2)i2 - (s-4)i)/2, as explained on the Wikipedia page "Polygonal Number". In this formula, positions start from 1, not 0, and we use the letter i to denote the position since we will be using the letter n for something else. For example, the sequence of "octagonal numbers" that springs forth from s = 8 starts with 1, 8, 21, 40, 65, 96, 133, 176... Given the number of sides s and an arbitrary integer n, this function should return the s-gonal integer closest to n. If n falls exactly halfway between two s-gonal numbers, return the smaller one. As you can see from the last row of the previous table, this function must be efficient even for gargantuan values of n. The simplest way to make this function efficient is to harness the power of repeated halving to pull your wagon with a clever application of…

(1 point) Consider the elliptic curve group based on the equation y² = x + ax + b x3 mod p where a = 2440, b = 295, and p = 3391. We will use these values as the parameters for a session of Elliptic Curve Diffie-Hellman Key Exchange. We will use P = (2, 808) as a subgroup generator. You may want to use mathematical software to help with the computations, such as the Sage Cell Server (SCS). On the SCS you can construct this group as: G=Elliptic Curve (GF(3391), [2440,295]) Here is a working example. (Note that the output on SCS is in the form of homogeneous coordinates. If you do not care about the details simply ignore the 3rd coordinate of output.) Alice selects the private key 18 and Bob selects the private key 15. What is A, the public key of Alice?…

Chirality def is_left_handed(pips): Even though this has no effect on fairness, pips from one to six are not painted on dice just any which way, but so that pips on the opposite faces always add up to seven. (This convention makes it easier to tell when someone tries to use crooked dice with certain undesirable pip values replaced with values that are more desirable for the cheater.) In each of the 23 = 8 corners of the cube, exactly one value from each pair of forbidden opposites 1-6, 2-5 and 3-4 meets two values chosen from the other two pairs of opposites. You can twist and turn any corner of the die to face you, and yet two opposite sides never spread into simultaneous view. This discipline still allows for two distinct ways to paint the pips. If the numbers in the corner shared by the faces 1, 2, and 3 read out clockwise as 1-2-3, that die is left-handed, whereas if they read out as 1-3-2, that die is right-handed. Analogous to a pair of shoes made separately for the left and…

Skydiving Bibi is a skydiving instructor. Before carrying out skydiving activities, Bibi will always ask the name, height, and age of the participants. Bibi's participants is always 2 people. To make it easier to remember their identities, Bibi gave them a paper to write down their identity. But because they are very enthusiastic in doing skydiving, they write their identity in a single line only (for both of the participants), so it wasn't quite neat and it made difficult for Bibi to see it, and resulted in the skydiving process being disturbed. As one of the organizer committee, you do not want this activity to be disturbed and plan to provide a program that provides their identity neatly to Bibi. Format Input Input consists of 1 line. It contains the identity of 2 people in a row Ni, Ti, Ui - the name, height, and age of the i-th participant. Format Output The output consists of 6 lines. The first line, "Name 1: N1". The second line, "Height 1: T1". The third line, "Age: U1". For…

Four in a row is a game in which players take turns adding tokens to the columns on the game board.   Tokens fall to the lowest position in the chosen column that does not already have a token in it. Once one of the players has placed four of their tokens in a straight line (either vertically, horizontally, or diagonally), they win the game If the board is full and no player has won, then the game ends in a draw.   TASK Using the following class descriptions, create a UML diagram and a version of Four in a row game   The game must allow for a minimum of two and maximum of four players The game must allow each player to enter their name(duplicate names should not be accepted) The game should give the players the ability to choose how many rows (between four and ten), and how many columns (between four and ten) the game board should have. The code uses several classes, including "Player", "Board","Game" and exceptions for handling errors such as invalid moves and full columns.…
