Question 2: The game of "FastestPath" consists of a path (a 1-D array) with n positive integers to represent n cities in a path (except the first index which has always value 0). The aim of the game is to move from the source city (located at index 0) to destination (located at last index) in the shortest time. The value at each index shows the travel time to enter the city located in the corresponding index. Here is a sample path where there are 6 cities (n is 6): |0 5 |90 | 7 61 | 12 Always start the game from the first city and there are two types of moves. You can either move to the adjacent city or jump over the adjacent city to land two cities over. The total travel time of a game is the sum of the travel times of the visited cities. In the path shown above, there are several ways to get to the end. Starting in the first city, our time so far is 0. We could travel to city 2, then travel to city 4, then travel to last city for a total travel time of 90 + 61 + 12 = 163. However, a…

Which of the following are correct regarding equivalence partitioning? a. b==c, a!=c and a, b and c belong to [1,10] always resulting in True b. a==b, a!=c, a, b and c belong to [0,10] resulting in True c. b==c, a!=b and a, b and c belong to [1,5] result in True d. a>b, b>c and a, b and c belong to [1,10] resulting in True e. a==b and a and b belong to [1,10] might be true or false depending on the value of c f. a==b, a!=c, is a valid partition always resulting in True

The wait-for graph scheme is not applicable to a resource-allocation system with multiple instances of eachresource type. We need a deadlock detection algorithm that is applicable to such a system. The algorithm employsseveral time-varying data structure that are similar to those used in the banker’s algorithm. Available. A vector of length ? indicates the number of available resources of each type. Allocation: An ? × ? matrix defines the number of resources of each type currently allocated to eachthread Request: An ? × ? matrix indicates the current request of each thread. If Request[i][ j] equals ?, thenthread ?i is requesting ? more instances of resource type ?jThe ≤ relation between two vectors denotes as follows:Let ? and ? be vectors of length ?. We say that ? ≤ ? if and only if ?[?] ≤ ?[?] for all ? = 1,2, . . , ?. For example,if ? = (1,7,3,2) and ? = (0,3,2,1), then ? ≤ ?. In addition, ? < ? if ? ≤ ? and ? ≠ ?.
