Q2. Consider the problem of generating all the possible permutations of length n. For example, the permutations of length 3 are: {1,2,33, {2,1,3),{2,3.1). {1,3,2). (3.1.2). (3.2,13. a) Well documented pseudocode of a recursive algorithm that computes all the permutations of size n. Calculate the time complexity of your algorithm using the big-Oh notation. Show all calculations b) Well documented pseudocode of a non-recursive algorithm that computes all the permutations of size n. The only data structure allowed is a queue. Any other memory usage should be O(1) Calculate the time complexity of your algorithm using the big-Oh notation. Show all calculations Q2.
