  • Simple if
  • if..else
  • Nested if
  • if..else ladder
  • Switch..Case Statement

6. Math.h Library 

Whenever you need to do a mathematical operation within the program, you need to include math.h library functions. This instructs the machine to perform a particular mathematical function. 

For example, if you use the sqrt() function, the machine will perform a square root operation on a particular value. You will learn about math.h library functions in this segment. 

  • abs(int x)

This part of the data structure module will give you an idea of stack implementation using an array and linked list.

  • Implementation of Stack using Arrays

Queue data structure is used for storing and managing data in a particular order. You can insert or remove an element from a queue by following the FIFO (First-in, First-out) principle. These can be implemented using arrays, linked lists, and stacks. You will learn the process of queue implementation using different data structures in this module.

  • Implementation of Queue using Arrays

17. Sorting, Searching, Hashing, Arrays, Strings

1/ Sorting Techniques

Binary search is the most efficient and fastest searching technique in a data structure that requires a sorted list to find an element among a given set of items.

What are the topics and concepts to learn in Data Structures and Algorithms?

1. Learn a programming language

The first step to learning data structure and algorithms is to learn at least one programming language. We start with learning C, as it is the base of all languages. However, you can choose any other languages of your choice, e.g., C++, Java, and Python. 

You must start with learning the fundamentals of language, including its basic syntax, data types, variables, conditional statements, loops, functions and more. We will cover all the essential topics related to C programming in our course. 

2. Time and Space complexity of an algorithm 

You must know the calculation of the time complexity of an algorithm that helps measure its performance. Another essential concept related to it is space complexity, which defines how much space or memory the algorithm is consuming. Having a clear understanding of time and space complexity ensures you can solve problems with the shortest and most efficient methods. 

3. Types of data structures

There are multiple types of data structures used in programming languages. You need to learn them all, including arrays, linked lists, stacks, queues, trees, graphs, hash tables, and heaps. Each of these data structures is used to insert and store data in an organised manner so that it can be processed and retrieved quickly and easily. However, they follow different techniques for each operation, and you must know them before implementing them in real life.

4. Sorting and Searching techniques

Data structure and algorithms are linked with each other. After you represent data using programming techniques, you need to use logical methods to manipulate them. To solve such problems, learning different sorting and searching techniques is essential. 

Sorting techniques (including bubble sort, insertion sort, quick sort, selection sort, and heap sort) are used to arrange elements in a data structure efficiently. This ensures your data are organised systematically. For example, you have a set of odd numbers {1,3,7,5,9}; after sorting, the data structure looks like {1,3,5,7,9}.

Searching techniques are mainly linear or sequential search and binary search that are used to locate an element in a data structure. Linear search is easy but a time-consuming process in comparison to binary search. However, you need to learn both of them: data structure and algorithm. 

5. Other types of algorithms

Besides Sorting and Searching algorithms, you need to master the techniques of several other algorithms. This includes divide and conquer algorithm, greedy methodology, backtracking algorithm, dynamic programming and more. Each of these algorithms uses different techniques and has varied time and space complexity.
