Data Science Hello @User so in this article, I am gonna explaining the topic "What is Data Science🤔", I also curious before about the topic until I didn't get it, so as we study bio in biology, maths in mathematics, just like that "Data science is the field of exploring data, analyzing, and using that data to answer the question or also make some recommendations". Data can also be in a structured manner and as well as an unstructured manner, in a structured manner, we can say data in excel or any other row column-wise so you can easily get insights of all data but in an unstructured manner, it will take some effort to be in structured then after you can analyze or visualize your data. Data Sources Primary data sources include data about collected and prepared directly by the researcher, such as investigations, questionnaires, polls. Secondary data sources include information regained through preexisting sources like research articles, Internet, web searches, et...

In this post, I am gonna show you how to find factorial of N numbers using recursion and as well as iterative approach, Here is the video clip of recursion that will visualize that how the recursion work.    Here's the code below in this code I have used input.txt and outout.txt for input-output purpose. and you can also use the code below and visualize using the recursion visualizer tool using this link https://recursion.now.sh/ Recursive approach It will take one integer value to find out the factorial and in this, we will take the first base condition, where the recursion will stop and we will get our final answer, and second which will create the stack size of the given number. Iterative Approach For the iterating approach, we just have to iterate the one variable "i" until we got the last number "n". and parallelly multiplying it with the "fact" variable which we have declared as "1" before.

So in this post, I am gonna show you how we can find the total sum of the given "N" natural number in the CPP program using recursive as well as iterative approach so let's begin. 1. using an iterative approach: In this approach, we will take 3 integers variables as below in the code first " n " for reaching the range of the last value and parallelly we will increment " i " with 1 add the sum in the " sum " variable and finally when the loop will break the condition we will get the final result.  Explanation: i = 0 , sum = 0   i = 1 , sum = 1   i = 2 , sum = 3   i = 3 , sum = 6   break Code 2. Using recursive approach: For example, in the below image the first n-1 elements sum + sum of the last element is equal to the sum of all elements, so sum(0) = 0 and sum of n > 0 = sum(n-1) + n using this approach sum function will call itself until it reaches to the last point at sum(0) base condition on which the recursion will stop and retur...
