Hello there! We will start this series of articles on the mathematical and other interesting things by the topic of Collatz Conjecture. Think of a number, let it be n . Now, is it even or an odd number? In case of an even number, just divide it by 2 or half it down, or multiply it by three and then add one. Still confused? Check out the example below. Let's say, you thought of a number n=5, Is 4 odd? yes. Multiply by 3 and then add 1, i.e. 4*3+1=13, Still odd, so, 13*3+1=40 40/2 = 20 , 20/2 =10, 10/2=5, 5*3+1=16, then it ends as 16 ... 8...4...2...1 The conjecture says that, every number will end as follows. Now, try that with 7, it will take about 16 steps, and for 27, it will take more than a hundred! But, there must be a law or a rule for them.. Here are a few values for different integers and the steps that it took for them to reach the 1. The above-mentioned output was given by the program which I wrote for the Collatz Conjecture, and the program ...
