Given an array, find 3 elements such that [a + b + c] = 0. Find all the 3 unique elements.

Given an array, find 3 elements such that [a + b + c] = 0.
Two solutions are possible: Iterative method and Two-pointer approach.
In the iterative method, we use three nested loops to find the combinations.
In the two-pointer approach, we sort the array and use two pointers to find the combinations.

My first day of learning DSA

I still remember the day I began learning DSA.
I was quite intimidated, probably due to the way it's often hyped up.
Data Structures and Algorithms (DSA) are foundational pillars in computer science.
Benefits of learning DSA include enhancing problem-solving skills, optimizing code, preparing for technical interviews, and gaining a deeper understanding of how software operates.

A Quick Guide To Status Code In Django REST Framework

Informational codes (100-199) are rarely used directly in DRF applications but are sometimes automatically managed by the framework.
Success codes (200-299) represent successful requests in REST APIs.
Client errors codes (400-499) indicate that the request from the client was invalid or couldn't be fulfilled by the server.
Server errors codes (500-599) indicate server errors in REST APIs.

Thoughts on Digital Ontology

The digital world often appears at the lower levels of being, with digital images and simulations being representations that are twice removed from reality.
However, the digital world can also act as a bridge to higher knowledge, particularly in fields like object-oriented programming.
By creating abstract classes that encapsulate universal principles, programmers can work with concepts that transcend the physical and approach universal truths.
To use technology wisely, we must reflect on how it shapes our perception of reality and strive to use it as a bridge to deeper truths.

Given an array of non repeating numbers and a key, find all the unique combinations in that array, where the sum of those combination is equal to the key.

Given an array of non-repeating numbers and a key, find all the unique combinations in that array where the sum of those combinations is equal to the key.
Example 1:
Input: Array = [2,3,6,7], key = 7
Output: [[7],[2,2,3]]
Example 2:
Input: Array = [2,3,5], key = 8
Output: [[2,2,2,2],[2,3,3],[3,5]]

Find the Container with Most Water explanation with diagram and solution

The problem requires finding a container that can hold the most water among the given set of vertical lines.
The solution involves calculating the area of all possible containers using the formula: Area = (right - left) * min(left_height, right_height).
A left pointer and a right pointer are used to iterate through the array and find the maximum area.
The time complexity of the solution is O(n), and the space complexity is O(1).

Given an input string (s) and a pattern (p), implement regular expression matching with support for ‘.’ and ‘*’.

The problem of regular expression (regex) matching has always fascinated computer scientists.
Regular expressions are patterns used to match character combinations in a string.
This article describes a solution to the problem of regex matching by using a bottom-up dynamic programming approach.
The solution uses a boolean 2D array to store the truth values and iterates through all the elements to fill the boolean array taking into account four possible conditions.
The time complexity of this solution is O(m*n) and the space complexity is also O(m*n).
An example is presented in the article to explain the solution in detail.
The final answer is true if the string matches the pattern.
This solution is implemented in C++.
Pattern and string can be matched using the implemented solution.
The code and output are well explained in the article with the help of images.
