SYSTEM AND METHOD FOR SUBSEQUENCE MATCHING

An embodiment of providing a computer-executed method of subsequence matching is provided. The method comprises receiving a search string. A plurality of subsequences for the search string are stored in a tree structure. The tree structure comprise a plurality of nodes. Each of the plurality of nodes comprises a presence bit map, a sequence bit map, and a list of address pointers. The method further includes traversing the tree structure using the search string, the presence bit map, the sequence bit map, and the list of address pointers. Additionally, the method includes identifying, in linear time, the plurality of subsequences based on the search string, the presence bit map, the sequence bit map, and the list of address pointers.
