WebLexicographic sorting of a set of keys can be accomplished with a simple Trie-based algorithm as follows: Insert all keys into a Trie. Print all keys in the Trie by performing preorder traversal on Trie to get output in lexicographically increasing order. Following is the C++, Java, and Python implementation of the idea. WebTwo keys are considered equivalent if the container's comparison object returns false reflexively (i.e., no matter the order in which the elements are passed as arguments). Another member function, map::count, can be used to just check whether a particular key exists. Parameters k Key to be searched for.

WebPython's OrderedDict is a dictionary subclass that remembers the order in which the items were added. The regular Python dict does not guarantee the order of the items when iterating over them, but OrderedDict does. This can be useful in situations where the order of the items matters, such as printing or storing data. http://duoduokou.com/python/32628584752280366208.html
