Question: An international round table conference will be held in india. Presidents from all over the world representing their respective countries will be attending the conference. The task is to find the possible number of ways(P) to make the N members sit around the circular table such that. The president and prime minister of India will always sit next to each other. Example 1: Input: 4 -> Value of N(No. of members) Output: 12 -> Possible ways of seating the members Explanation: 2 members should always be next to each other. So, 2 members can be in 2!ways Rest of the members can be arranged in (4-1)! ways.(1 is subtracted because the previously selected two members will be considered as single members now). So total possible ways 4 members can be seated around the circular table 2*6= 12. Hence, output is 12.

5. .simple Such a here As part of your ICS 2 internship, you are joining a growing start-up company. The startup is hoping to expand its technical team and arelooking for junior developers. Your manager wants you to be involved in the interview process for the appointment.You are asked to design a coding interview question in Python / C++ / Java that tests a candidate's knowledge and skill in both basic datastructures and algorithms. Along with the question, you also need to develop sample solutions with complexity analysis of the problemincluding Python / C++ / Java codes and test cases.Since your manager will only allow a maximum of 1 hour for the interview, 45 minutes will be allocated for this technical element, so theproposed exercise should be concise, clear and cover at least 2 of the following topics:• Topic 1: Basic data types: array, list, stack, queue• Topic 2: Trees• Topic 3: Recursion• Topic 4: Sorting• Topic 5: General Programming Questions.You also need to provide…
Having covered the same concepts in C++ & Python, and having completed hands-on exercises and Lab Sheet programs, You, must have realized that there are differences between C++ & Python in many ways. Specifically, for the following 10 areas shown in the table below, discuss how Python is different than C++ Area of Comparison Python C++ Execution (1 issue) |(Steps needed to run a Program) Syntax (4 issues) Variables (4 issues) Collections (3 issues) Operators (3 issues) Conditionals (2 issues) Loops (2 issues) Functions (2 issues) Modules (2 issues) The Variables Scope (1 issue) Notes: - Number of “issues" indicate minimum number of differences in each area of comparison.

Note: Please answer the question in C++ only: Rajesh recently revamped its practice page to make it easier for users to identify additional problems to solve by introducing some new features: Recent Contest Problems - contains only problems from the last 2 contests Separate Un-Attempted, Attempted and All cards Problem Difficulty Rating - The Featured drop-down menu has different difficulty ranges so you can try problems that best suit your experience. Popular topics and brands Like most users, Chef didn't know that he could add problems to his personal to-do list by clicking the magic "+" symbol in the upper right corner of each problem page. But once he found out about it, he went crazy and added a lot of problems to his to-do list without looking at their difficulty rating. Rajesh is a beginner and ideally should only try to solve problems strictly below 10001000. Given the difficulty rating list of problems in Chef's to-do list, please help him determine how many of these problems…
