Course Description

What is the difference between data structure and algorithm?
Data Structure is about organising and managing data effectively such that we can perform specific operation efficiently, while Algorithm is a step-by-step procedure to be followed to reach the desired output. ... Steps in an algorithm can use one or many data structure(s) to solve a problem.What is algorithm used for in data structure?
Algorithm is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output. Algorithms are generally created independent of underlying languages, i.e. an algorithm can be implemented in more than one programming language.What are the different types of data structures?
When we think of data structures, there are generally four forms:
Linear: arrays, lists.
Tree: binary, heaps, space partitioning etc.
Hash: distributed hash table, hash tree etc.
Graphs: decision, directed, acyclic etc.How do you use data structures and algorithms?
7 steps to improve your data structure and algorithm skills
Step 1: Understand Depth vs. Breadth. ...
Step 2: Start the Depth-First Approach—make a list of core questions. Identify a list of ~100 core problems. ...
Step 3: Master each data structure. ...
Step 4: Spaced Repetition. ...
Step 5: Isolate techniques that are reused. ...
Step 6: Now, it's time for Breadth. ...
Step 7: Practice on paper.What are the 2 main types of data structures?
There are two fundamental kinds of data structures: array of contiguous memory locations and linked structures.What are the 5 properties of an algorithm?
An algorithm must have five properties:
Input specified.
Output specified.
Definiteness.
Effectiveness.
Finiteness.
