Give an O(n2 ) algorithm (Pseudocode) that, given a sequence S, finds the longest subsequence that first increases then decreases. For instance, in the sequence S = [10, 4, 5, 11, 2, 7, 4, 3, 9] the longest such subsequence is [4,5,11,7,4,3]. The subsequence does not have to be consecutive. (Hint: Use two arrays, one for increasing subsequences and the other for decreasing subsequences.)

Let S be a sequence of n distinct integers stored in an array as array elements S[1], S[2], · · · , S[n]. Use the technique of dynamic programming to find the length of a longest ascending subsequence of entries in S. For example, if the entries of S are 11, 17, 5, 8, 6, 4, 7, 12, 3, then one longest ascending subsequence is 5, 6, 7, 12. Specifically: (a) define a proper function and find the recurrence for...

Let's say you are given a sequence of distinct positive numbers. We want to find a subsequence with the maximum possible sum, with the restriction that we are not allowed to take three consecutive elements from the original sequence. For example, for input 1, 6, 5, 2, 7, 9, 3, 4, the subsequence with the maximum possible sum is 6, 5, 7, 9, 4 (we have two pairs of consecutive elements 6, 5 and 7, 9 but not three consecutive...

You are given a sequence of integer values. Describe an algorithm requiring no worse than O(n2) time for finding the length of a longest rising subsequence in that array. A subsequence is rising when each element is less than or equal to the one following it. For example, in the sequence [23, -15, 10, 25, 7, 32], the length of a longest rising sequence is 4, found in the subsequence [-15, 10, 25, 32].

Use the following sequence as the list to sort: [ T, H, A, N, K, F, U, L ] You need to display the contents of the list during the execution of the algorithm. a) Sort the list using selection sort. b) Sort the list using heap sort. You do not need to draw the heap diagram unless you find it helpful, but you must still show the contents on the list during execution. c) What is the worst-case runtime...

(20 points) You are given an array A of distinct integers of size n. The sequence A[1], A[2], ..., A[n] is unimodal if for some index k between 1 and n the values increase up to position k and then decrease the reminder of the way until position n. (example 1, 4, 5, 7, 9, 10, 13, 14, 8, 6, 4, 3, 2 where the values increase until 14 and then decrease until 1). (a) Propose a recursive algorithm to...

Show the element sequences of running Shellsort on the input {15,2,8,1,10,7,4,3,9,11,12,6} at the increments {7, 3, 1}, respectively. 3.
