Study guide
In this lab you turn the theory into working programs: array insertion and deletion, matrix addition, subtraction and multiplication, singly linked list insertion and deletion at the beginning, end and a specified position, doubly and circular linked lists, stack push and pop with arrays and linked lists, postfix evaluation using a stack, recursive factorial and simple and circular queue operations. Test each program with an empty structure, a single element and a full structure, since edge cases are where bugs hide.
Why Data Structures-I Laboratory Matters
Implementing structures yourself is the best way to understand them, and these programs are the classic exercises in coding rounds. Students who can write a linked list or stack from scratch stand out in interviews.
How to Prepare for Data Structures-I Laboratory
- Write each program without looking at the solution first, then compare.
- Test with empty, single-element and full structures.
- Prepare viva answers on time complexity of each operation.
