goto statement in C++

In C++, the goto statement is a jump statement used to transfer unconditional control to a specified label. In other words, it allows you to jump from any starting point to any ending point in a program, altering the program's flow.

Three dimensional (3D) array in C

A 3D array is a multi-dimensional array (array of arrays). A 3D array is a collection of 2D arrays. We have explored 3D arrays in C in depth from defining such array along with basic operations.

Software Engineering

Two dimensional (2D) array in C

In this article, we have explored 2D arrays in C including declaring 2D array, calculating size, inserting elements and updating 2D array, convert 3D array to 2D array and using malloc to define 2D arrays in C.

Exploring Python's Stat Module

Python's stat() module performs a stat system call on the given path and provides several information like inode number, size, number of hard links, time it was created and modified and much more.

Algorithms

Topological Sorting using Kahn's Algorithm

We have explored topological sorting using Kahn's algorithm. The basic idea is that a DAG G has at least one vertex with in-degree 0 and one vertex with out-degree 0.

Understanding Rate Limiting in Node.js

Rate limiting is a powerful feature that secures the backend API from malicious attacks and is also used for handling unwanted traffic(requests) from the user.

Algorithms

Smallest Palindrome greater than N using the same set of digits

We are given an number and we have to find the smallest pallindrome number greater than N which can be formed by using the same set of digits as in N. We have solved this using a Greedy approach in linear time.

Algorithms

Closest string such that no two consecutive characters are same

We are given a string and we have to find the closest string such that no two characters in the string are same. This problem can be solved using a simple greedy approach which will take linear time O(N) and constant space O(1).
