Algorithms and data structures are the most important subjects in a programmer's life if they want to make money in the programming world.

A programming algorithm is a solution-finding procedure or formula. All programming languages are based on algorithms, which provide a precise definition of the program.

Let's take a look at some of the most common algorithms that you ought to have at least a fundamental understanding of before going in for coding interviews.

1. Tree Traversal Algorithms

Trees are a linked-node data structure with a root node and sub-trees. These algorithms allow structured tree node visits.

2. Binary Search

When given a sorted array of elements and a search key, binary search works. It's a simple concept that's simple to grasp and put into practise.

3. Linear Search

It works by starting with the 0th element and comparing the user's input element to each term before returning the element's position.

4. Search Algorithms

This class of algorithms only has binary search. These algorithms underpin databases, virtual spaces, substructures, and quantum computers.

5. Sorting Algorithms

These algorithms arrange data to make meaning. Merge sort and quick sort are popular in this class.

6. Dynamic Programming

By storing previously calculated values and using them as needed, dynamic programming or memorization eliminates problems.

7. Quick Sort

Quicksort uses the last element as the pivot number, placing smaller numbers on the left and larger ones on the right.

8. Bubble Sort

It's a sorting algorithm that relates two adjacent elements and swaps them around until they're no longer in the right order.

9. Hashing Algorithms

Hash algorithms accept any data as input and use a hash table to generate a message that is consistent regardless of the data.

10. Graph Search Algorithms

Graphs, like trees, are non-linear data structures with nodes connected by edges. These work on trees, vertices-and-edges graphs, and any graph encoding.
