Fibonacci Sequence

                            A Fibonacci sequence is a series of numbers that starts with a zero, followed by a one, and proceeds based on the rule that each number(called a Fibonacci number) is equal to the sum of the preceding two numbers. 0,1,1,2,3,5,8,13,21,34,… •It starts with 0 & 1. •The next number 1 is found by adding the two numbers before it(1+0). •Similarly, the number 21 is found by adding the two numbers before it(13+8). •And the number 34 from (21+13). •And so on… Here is the list 0,1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597, 2584,4181,6765,10946,17711,28657,46368,75025,121393, 196418,317811,.... Step1 :Input the number (n) till which the Fibonacci series will run Step2 :Let assign a variable a equal to -1 and b equal to 1 Step3 :We add variable a & b and assign it to variable x Step4 :Display the value of x Step5: Assign the value of b to va...

Flowchart

What is a flowchart?                      A flowchart is a diagrammatic representation of boxes of various kinds  that are connected by arrows to solve a particular problem.                       A flowchart is a type of diagram that  r epresents an algorithm, workflow or process.It is used in analysing,  designing, d ocumenting or managing a process in  v arious fields. Flowcharts have become a popular means for  d escribing computer algorithms. Why use a flowchart?                 It is more effective to  visualise  something graphically  t han it is to describe it with words. Flowchart explain  a process more clearly through symbols and text. To see the working of the above flowchart watch video Click here to Watch on YouTube ...

Algorithm

What is an algorithm? Algorithm is a set of simple steps written to solve a particular task. There can be many task from waking up to going to school, logging on to a gmail account or finding prime numbers etc. For example write an algorithm for logging onto gmail account and checking your mails. STEP1:Open a browser in your desktop/laptop STEP2:Write gmail address www.gmail.com on address bar url of browser. STEP3:Login onto your gmail account with your username and password STEP4:Check your mails if your username and password is correct STEP5:After doing your work on gmail account, logout. Algorithm is a step-by-step list of directions that need to be followed to solve a problem. A recipe can be considered as a type of algorithm.It tells what ingredients are needed to make the dish and what steps to follow.There can be many different recipes to make a certain dish which looks different but ends up tasting the same when all is said and done. The sam...
