Algorithms In C++ Parts 1-4

The algorithms included here cover a broad range of fundamental and more advanced methods: sorting, searching, string-processing, geometric, graph, and mathematical algorithms. Readers will see how key algorithms can be implemented, run, debugged, and used in real applications--plus why some algorithms are to be preferred over others.
