DATA STRUCTURES PRELIM EXAM
QUESTIONS WITH CORRECT
ANSWERS
Data Structure - Correct Answers -- A systematic way to organize data in order to use it
efficiently.
Interface - Correct Answers -- Each data structure has this.
- It represents the set of operations that a data structure supports.
- It only provides the list of supported operations, type of parameters they can accept
and return type of these operations.
Algorithm - Correct Answers -- Is a step-by-step procedure, which defines a set of
instructions to be executed in a certain order to get the desired output.
- They are generally created independent of underlying languages, i.e. it can be
implemented in more than one programming language.
Search, sort, insert, update, delete - Correct Answers -5 important categories of
algorithms
Data Structures & Algorithms - Correct Answers -- They are two of the most important
aspects of computer science
Why we need to study DSA - Correct Answers -- DSA enables you to solve real-world
problems
- DSA helps in writing Optimized Code
- DSA opens up the path to becoming a Computer Scientist
- Improves Adaptability to Emerging Tech Stacks
- Helps you crack the top tech companies
Feasibility - Correct Answers -Should be feasible with the available resources.
Independent - Correct Answers -An algorithm should have step-by-step directions,
which should be independent of any programming code
Priori Analysis - Correct Answers -This is a theoretical analysis of an algorithm.
Efficiency of an algorithm is measured by assuming that all other factors, for example,
processor speed, are constant and have no effect on the implementation.
