greedy and lazy regular expressions (comprehension question)

A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time. WebIt's not the shortest possible match, just a short match. Greedy mode tries to find the last possible match, lazy mode the first possible match. But the first possible match is not necessarily the shortest one. Take the input string foobarbaz and the regexp o.*a (greedy) or o.*?a (lazy). The shortest possible match in this input string would be ... slowdive original album classics https://scrsav.com
