Data Structures Tutors & Algorithms Experts Online

Looking for an Online Data Structures Tutor?

Some popular concepts of data structures like arrays, queues, and trees are easy to understand conceptually but often are confusing while coding. We have expert data structure tutors that help you understand and apply various concepts of data structure to build your skills as a developer. We have live 1:1 sessions with experienced mentors who can guide you as per your capabilities.

What are Data Structures & Algorithms?

Data structure is a concept of computer science that is used to store and organize data to be more structured. This allows the data to be accessed more easily and efficiently. Some common data structures are stacks, queues, and arrays.
An algorithm on the other hand is a series of steps that are used to solve any problem, an algorithm is defined to make programming a solution easy. An algorithm is unique to its problem statement. For example, an algorithm for adding 2 numbers would be -
Step 1: Take 2 numbers as input
Step 2: Create a variable sum and initialize it to ‘0’
Step 3: Add both numbers and assign their result to sum

Why Learning DSA is Important?

DSA stands for data structures and algorithms, the core subjects in any programming language are essential to building any project. The choice of DSA can determine various factors of a problem/project such as its efficiency, time complexity, space complexity, and functionality. The DSA chosen for every project/software/ algorithm is unique to its problem statement, if time needs to be saved then a different approach is used, if space needs to be saved then a different approach is used for the same problem. DSA also builds the critical thinking of a developer as it pushes them to think through various methodologies and choose the most viable solution to the problem.

Key Topics where Students need Expert Assistance

Each student has their level of understanding and experience in the field of computer science but some major topics that may be difficult to grasp are:

• Queues: It is a type of data structure that follows the FIFO principle(first in, first out). Here the elements which are added first are removed first.
• Stack: It is a type of data structure that follows FILO( first in, last out). Here the elements which are added first are removed last. You can learn about the difference between stacks and queues in this blog.
• Linked lists: These are a series of elements that point to the element next to it, for example, imagine a train with various compartments, and they are all linked together. They are 2 types of linked lists, single which points to one the element next to it, and double linked list which points to elements on both sides.
• Trees: These are collections of nodes that are arranged hierarchically. The structure resembles branches of a tree all starting with a root node.
• Hash tables: These are a type of data structure that uses a hash function to map the various keys within associative arrays.
• Dynamic programming: It is a technique where a complex program is broken into smaller pieces, each piece is then solved individually and the solution is stored in an array that can be later reused as per requirements.
• Greedy technique: It is a technique that finds the best local solution at every step of the problem in hopes to get the global optimal solution. It used mainly in optimization problems
