Overview & Analysis
Programming and Data Structures (DS) is a fundamental subject in GATE CS, contributing 8 to 10 marks. It tests structural layout efficiency and algorithmic operations in C.
GATE questions require evaluating pointer logic, recursion in C, array indexes, linked list insertions/deletions, binary search trees (BST), AVL trees, heap structures, and hashing tables.
Frequently Asked Questions (FAQ)
Q: What aspects of C programming are tested in GATE?
A: Expect questions on pointer arithmetic, parameter passing (call-by-value vs. call-by-reference), multi-dimensional arrays, recursion, and string manipulation functions.
Q: What are the key properties of a Binary Search Tree (BST)?
A: In a BST, for every node, all elements in the left subtree are smaller and all elements in the right subtree are larger. Crucially, the in-order traversal of a BST always yields sorted elements in ascending order.
