A beginner of the Data structures, who has some basic knowledge of C, could find this book interesting and simple. Every program has a proper step by step explanation of each line of code. It contains the practical implementation of stacks, queues, linked lists, trees, graphs, searching and sorting techniques. Also, recursion has been explained in an easy manner with the numerous examples. However if you find any mistake, or want to give some suggestions for the improvement of this book, then the same may be sent at '[email protected]', so that the mistakes may be rectified and the suggestions may be incorporated.
