In computer programming and computer science, "maximal munch" or "longest match" is the principle that when creating some construct, as much of the available input as possible should be consumed.

WebI want to clear things up by saying that the maximal munch scan _will_ find valid tokens in both cases. In the first example, maximal munch will find 7 tokens 'list', '<', 'list', '<', 'int', and '>>' These are all valid tokens. So the scanner did its job. The problem is that this sequence does not correspond to valid c++ code.
