solve the problem in java: Consider the are n=2 subjects and needed =[4,5] answered questions, to pass. The student has answered =[2,4] questions in the two subjects so far, and can answer another q=1 questions across all subjects combined. The best outcome is to answer an additional question in the second subject on order to pass it, as 2 more answers required to pass the first subject. the max number of subject s that can be passed is 1. the function must return an integer that can represent the max number of subjects that can be passed. public static int maxNumsub(List answered, List needed, int q) { //write code here }

Let's revisit our first problem, where we want to set up a series of chess matches so we can rank six players in our class. As we did before, we will assume that everyone keeps their chess rating a private secret; however, when two players have a chess match, the person with the higher rating wins 100% of the time. But this time, we are only interested in identifying the BEST of these six players and the WORST of these six players. (We don't care about the relative ordering or ranking of the middle four players.) Your goal is to devise a comparison-based algorithm that is guaranteed to identify the player with the highest rating and the player with the lowest rating. Because you are very strong at Algorithm Design, you know how to do this in the most efficient way. Here are five statements. A. There exists an algorithm to solve this problem using 6 matches, but there does not exist an algorithm using only 5 matches. B. There exists an algorithm to solve this problem using 7 matches,…

What Python code will solve the following: The goal of this section is to estimate the probabilities Pij (transition probabilities) associated with finding food from any location (i, j) inside the maze. A rat will be considered successful in finding food if the probability of finding food from a given location exceeds 0.5. 1. Use Equation (1) to write down equations for each probability Pij for i = 1, 2, · · · , 6, j = 1, 2, 3, · · · , 5. Equation 1 is : Pij = 1/4Pi-1j + 1/4 Pi+1j +1/4 Pij-1 + 1/4Pij+1 2. Notice that your equations constitutes a system of linear equations with 30 equations and 30 unknowns, with the unknowns as the transition probabilities. Identify the coefficient matrix for the system of equations and write your system in the form Ap = b, where b is some constant vector and p the vector of transition probabilities, ordered from the upper left hand corner of the maze to the lower right hand corner. The goal is to solve the system for p. 2 3. How would you characterize…
