The randint() Method in Python
Introduction In this tutorial, we are going to focus on the randint() method in Python. In our previous tutorials, we saw different random number generating methods defined inside the random module in our Random Number….
Open System Interconnection Model (OSI Model) is a 7 layered architecture structure to transmit the data from one point to another point. It is basically a reference model that interprets how the data from one….
Depth First Search (DFS) for a Graph
Depth First Search (DFS) is an algorithm that searches a graph/tree, in a depth-wise manner. There are many ways through which we can traverse through a graph. The two most common methods that we can….
The apply(), sapply(), lapply() and tapply() Functions in R Programming
The family of apply() functions in R is used to apply user-defined functions to the elements of complex structures like matrices, lists or data frames. These functions help a lot in simplifying your code and….
Lists in R Programming
Lists in R can group together different kinds of variables into a single compound structure. For this reason, lists prove very useful in handling data. A list can contain a numeric, integer string, factor or….
Arrays in Shell Scripts
Knowing how to work with arrays in shell scripts will help you work with larger datasets in a much efficient manner. But what are arrays and how can you create arrays? Let’s find out! What….
Ways to Concatenate Lists in Python
In this tutorial, we will unveil different methods to concatenate lists in Python. Python Lists serve the purpose of storing homogeneous elements and perform manipulations on the same. In general, Concatenation is the process of….
Basics of Graph Theory
In this article, we’ll touch upon the graph theory basics. Graph Theory is a branch of mathematics that aims at studying problems related to a structure called a Graph. In this article, we will try….
Reverse String in C++
In many situations, we may need to reverse a string in C++ programming. It may include just printing a reversed string. Or maybe in some cases need to reverse the string permanently at its address…..
Data frames in R Programming
Let’s continue in our R programming tutorial series, and understand data frames in R. If you have ever handled data in databases, you will be familiar with the idea of records. Records are nothing but….
