Randomized Select Algorithm

A randomized algorithm is defined as one that uses a certain amount of randomization in its logic or operation. It is said to be an algorithm that depends on the random number to perform its operation. It is used for reducing the overall time complexity, space complexity in the standard algorithm. The randomized algorithm uses the concept of random numbers to find the solutions to the different kinds of problems and also to improve the problem solutions.

Rohan is a huge soccer fan so he wants to catch a game of the UEFA Champions League (UCL) while he is in Europe. Assume UCL has k participating teams, where k is a positive even integer. Suppose that the organizer of the league decides that there will be a total of k2 matches this season, where no pair of teams plays more than once against each other (ie. if Paris and Barcelona play a match against each other, they never play against each another again for the rest of the season). Prove that if every team has to play at least one match this season, then there is no team that plays two or more games.
You are given the arrival and departure times of trains reaching to a particular station. You need to find minimum number of platforms required to accommodate the trains at any point of time. Trains arrival = [9:00, 9:40, 9:50, 11:00, 15:00, 18:00] Trains departure = [9:10, 12:00, 11:20, 11:30, 19:00, 20:00] The situation can be solved by using few algorithms. However, it will reflect the complexity of the solution. You are required to solve the problem using, (b) Greedy Algorithm i) Produce the complete algorithm ii) Calculate the minimum number of platforms based on algorithm in (b)(i) and show the process.
