Trees for GATE CS

Trees are used for data storage purposes and have nodes at their edges. Going by the trees book, you must know the basic types of operation performed on the tree having two or more children nodes. Operations such as insert, search, postorder traversal, inorder traversal and preorder traversal can be performed on binary trees. You can also traverse between any given nodes and change your levels. Initially, we start with the binary trees having two nodes, then branch off on multi-node trees.

Trees GATE questions come in many exams, including CAT, GATE CS, PDU CS, SDE interviews and more. Trees online tests also form a part of various state and national level exams.

FAQs

Q. What do you understand by trees?

The tree is an organised data storage place where we can perform different operations to retrieve and modify the stored data.

Q. What is the importance of trees?

Trees provide a hierarchical data structure organised, hence improving search time and loading speed.

Q.Which other exams, trees are asked other than GATE?

The tree is an essential topic and is asked in other exams such as PSU CS, CAT, SDE roles, etc. It helps in the understanding of compilers' work.

Q. How many types of operations can be performed on the binary tree?

We can perform different operations such as insert, search, postorder traversal, inorder traversal and preorder traversal.

Q.What is the INSERT operation used for?

INSERT element adds data in relevant nodes. The first insertion creates the tree with the mother node. With subsequent insertion, you go on creating child nodes.
