6 Algorithms Every Developer Should Be Aware Of

Hello, I'm a programmer, and you should know that I'm not particularly fond of data structures and algorithms. Don't worry; after working on numerous projects (both small and huge), I identified the six key algorithms that every developer should know, and these six will nearly always solve any difficulty in your development process.

1. Algorithm for Sorting:

Algorithm for Sorting

Sorting, what precisely is it?

  • The algorithm determines the order of the elements in a list.

Significant Sorting Algorithms-

  • Bubble Sort is the simplest basic sorting algorithm, and it operates by exchanging nearby components if they are out of order frequently.

  • Merge sort is a sorting technique that use the divide and conquer approach.

  • Quicksort is a common sorting algorithm that, on average, performs n log n comparisons when sorting an array of n entries. It is a quicker and more efficient sorting method.

  • Heap Sort: Heap sort visualises array items as a specific form of full binary tree known as a heap.

2. Algorithm for Searching:

Algorithm for Searching

What precisely is looking for?

  • The algorithm is responsible for locating an element in a data collection.

Important Algorithms for Searching-

  • Binary Search: The divide and conquer approach is used in binary search, in which a sorted list is divided into two halves and the item is compared to the list's middle element. If a match is detected, the position of the middle element is returned.

  • Breadth-First Search (BFS): A graph traversal technique that starts at the root node and searches all nearby nodes.

  • Depth-First Search (DFS): The depth-first search (DFS) method starts at the top of the network and works its way down until it finds the goal node or node with no children.

3. Dynamic Programming:

Dynamic Programming

Dynamic Programming (DP) is an algorithmic approach for addressing optimization issues by breaking them down into simpler sub-problems and exploiting the fact that the optimal solution to the overall problem is reliant on the best solution to its sub-problems.

4. Algorithm of Recursion:

Algorithm of Recursion

Recursion is a problem-solving strategy in which the solution is determined by the solutions to smaller instances of the same problem. Factorial computation is a famous example of recursive programming.

Every recursive programme goes through the same fundamental steps:

  • Configure the algorithm. To begin with, recursive programmes often require a seed value. This is achieved by either passing a parameter to the function or by supplying a non-recursive gateway function that sets up the seed values for the recursive computation.

  • Check to determine if the current value(s) being processed match the base case. If this is the case, process the value and return it.

  • Resolve the problem in terms of a smaller or simpler sub-problem or sub-problems.

  • Use the algorithm to solve the sub-problem.

  • Combine the results to come up with an answer.

  • Please return the findings.

5. Divide and Conquer:

Divide and Conquer

A divide-and-conquer algorithm separates a problem recursively into two or more sub-problems of the same or related kind, until they are simple enough to tackle directly.

The Divide and Conquer algorithm involves a debate that follows the three phases described below.

  • Break the original problem down into sub-problems.
  • Conquer: Solve each sub-problem iteratively one at a time.
  • Combine: Combine the answers to the sub-problems to acquire the solution to the overall problem.

6. Hashing:


Hashing is a technique or procedure that maps keys and values into a hash table using a hash function. It is done to provide faster access to components. The efficiency of the hash function determines the efficiency of mapping.



With so many algorithms of various complexity accessible, determining which ones are genuinely vital to comprehend is tough. It frequently comes down to personal opinion and viewpoint, but this article has highlighted various algorithms that developers should be aware of.
