What if my movie marathon consists of exactly five distinct movies: two movies from one of the trilogies, 2 movies from a 2nd trilogy, and 1 movie from a 3rd. The movies can be watched in whatever order I choose and the same five movies watched in a different order constitute a different marathon. Now how many movie marathons are possible?

The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Note: Please Answer in java language only. Input 1 1 hasan jaddouh Output hasan
You want to cut a rectangular pan of brownies, made up of n square-shaped brownies, but you can only make horizontal or vertical cuts. Assuming you can only make one cut at a time, how many cuts will you need to split the pan into n individual brownies? Use strong induction to prove your answer.
Using Python programming language. There are exactly N people living in a certain parallel universe. The Ith of these N people claim to be the parent of exactly Ai off these N people. However, some of these people may be lying - the person may either be telling the truth (in which case they have exactly Ai children) or lying down (in which case they can have any number of children). It is known that each person has at most one parent. Furthermore, as one would expect, a person's child is not allowed to also be their ancestor. What is the maximum possible number of truth tellers in this universe Required Output 2 Possible input 1 2 10
Answer the following questions given the figure (topic is about the A* algorithm):Legend:P=Player/Starting pointO=ObstacleG=Goal Given the figure, do the following:1. Mark each cell with its heuristic function h, using the "as the bird flies" distance. Use integers only.2. Show how the player (P) will reach the goal (G). For every cell planned for the player movement, show the updates f,g,h of its non-obstacle neighbor cells.
6. You have taken a new job with a small marketing platform. Their main line of business is to send marketing messages to people on their extensive email list. The messages are not cheap; companies wanting to send messages must purchase them individually while specifying certain groups of people to receive them. Of course, nobody likes spam, so you try to make sure each person receives at most one marketing email a day. Suppose at the start of the day you are given a list of m messages, a list of n email addresses, and a table specifying which messages can be sent to which email addresses. Describe and analyze an algorithm that computes the maximum number of marketing emails you can send so each individual message is sent at most once and each email address receives at most one message. Advice: Reduce the problem to bipartite matching or maximum flow.
Correct answer will be upvoted else downvoted. Computer science. You are given a positive (more noteworthy than nothing) integer n. You need to address n as the amount of integers (conceivably negative) comprising just of ones (digits '1'). For instance, 24=11+11+1+1 and 102=111−11+1+1. Among every conceivable portrayal, you need to track down the one that utilizes the base number of ones altogether. Input The single line contains one integer n (1≤n<1050). Output Print one integer x — the base number of ones, to such an extent that there exist a portrayal of n as the amount of integers (perhaps bad) that utilizes x ones altogether.

There are 2 best friends and they both jumped into the crowd. Chris Martin points to N number of followers one at a time. Imagine endless fans arranged with a 2D infinte grid, with each follower standing at each step in an orderly fashion. Chris gives them directions in the form of an S unit and they follow blindly. As a result, few fans appear with more than one T-shirt. They start at the same place (bring two T-shirts to the same starting fan), and take turns based on orders from Chris, who gives them orders as follows: U- Move up the stairs, D - Go Down one step, L- Go Left one step, R - Go Right one step Given the S-let unit of the instructions given to Chris. Which brings out the number of lucky fans who have received at least one T-Shirt using java code. Input: 2 UD Output: 3

Electronic Spreadsheet Applications Compare What-If Analysis using Trial and Error and Goal Seek to the given scenario: Let's say a student is enrolled in an online class at a learning institution for a semester. His overall average grade stands at 43% in the course (Term Grade is 45%, Midterm Grade is 65%, Class Participation is 62% and Final Exam is 0%). Unfortunately, he missed his Final Exam and was given 0%. However, he has the opportunity to redo his Final Exam and needs at least an overall average of 60% to pass the course. How can you use Trial and Error and Goal Seek to find out what is the lowest grade he needs on the Final Exam to pass the class? Which method worked best for you and why?
Consider a world on which each individual belongs to a family of six, each family resides in its own home, each house has a specific address and every person in a certain house is given a unique name.Assume that this world has a postal service providing letters from source to destination. The postal service needs (1) the letter to be in an envelope and (2)that the address (and nothing else) of the destination house be clearly shown on the envelope. Suppose each family has a delegated member who receives letters for the other family members and distributes them. The letters do not actually give the receivers of the letters a hint. a. Would the postal service.ever have to open the envelope and inspect the letter and include the service under your protocol?
