UNIT – III:

Multiway trees, B-Trees, 2-3 trees, 2-3-4 trees, B* and B+ Trees. Graphs, Graph representation, Graph traversal.

UNIT – IV:

Sorting concept, order, stability, Selection sorts (straight, heap), insertion sort (Straight Insertion, Shell sort), Exchange Sort (Bubble, quicksort), Merge sort (only 2-way merge sort). Searching – List search, sequential search, binary search, hashing concepts, hashing methods (Direct, subtraction, modulo-division, midsquare, folding, pseudorandom hashing), collision resolution (by open addressing: linear probe, quadratic probe, pseudorandom collision resolution, linked list collision resolution), Bucket hashing.

Data Structure simply corresponds to Structure of data that helps in implementing the best solution to solve a particular problem. A data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. There are many types of data structure like array, link list, stack, queue, tree and graph.

The choice of data structure depends on two considerations.

it must be rich enough in structure to show the actual relationships of data in real world.
data structure should be simple enough so that one can process the data when necessary.

Primitive Data Structure: Integer, Float, Character, Pointer, Double.
