Data Structure is one of the  important subject for students of Computer Science. Some questions are asked every year from Data Structure in GATE/NET exam. This subject covers the topics like Array, Queue, Stack, Link List, Tree, Graph, Sorting and Searching.  

In this post some important questions from Data Structure are as follows:
