WebAt least asymptotically, it is slower: if m and n are the lengths of the small and large sequences, building sets and testing for inclusion is O(log(m+n)) whereas testing subsequence inclusion is O(m+n) with a clever algorithm like KMP. WebA simpler problem is to find the length of the longest increasing subsequence. You can focus on understanding that problem first. The only difference in the algorithm is that it doesn't use the P array.. x is the input of a sequence, so it can be initialized as: x = [0, 8, 4, 12, 2, 10, 6, 14, 1, 9, 5, 13, 3, 11, 7, 15]. m keeps track of the best subsequence of …

A naive solution would be to cycle through all subsets of n numbers and, for every one of them, check if the subset sums to the right number. The running time is of order O(2 n.n) since there are 2 n subsets, and to check each subset, we need to sum at most n elements..

Generating all subsequences of an array/string is equivalent to generating a power set of an array/string. For a given set, S , we can find the power set by generating all binary numbers between 0 and 2 n -1 , where n is the size of the given set.
