"Nettet13. apr. 2024 · Assume T(t,p) is the time complexity of function isMatch(text, pattern) where t is text.length() and p is pattern.length() / 2. First T(x,0) = 1 for all x. Then if pattern[1] == '*', T(t,p) = T(t,p-1) + T(t-1,p) + O(t + p). Otherwise T(t,p) = T(t-1, p-0.5) + O(t + p). Obviously the first case is worse. Think about the Combination Meaning of T. ...

Nettet21. mai 2024 · 1 Answer. First of all, the complexity of algorithms depend upon the data structures used. The complexity of BFS and DFS are O (V+E) only when you use adjacency list representation of graph. Secondly, the code does not maintain a visited set of nodes which is referenced to backtrack, and not to re-visit the same nodes.
