Something I am constantly wanting to do in a lot of programs is see if a value is in an array. For another function which I wish to write to add to the Zeller program this will come in handy. The basic algorithm looks like this: SET value TO RequiredValueSET array TO ArrayToSearchSET isIn TO …

Factoral and Recursion
We all remember factorals from school but to remind us what they are, a factoral is the product of all the positive integers less than or equal to the initial number(n): For example: Strangely 0!=1 there is a mathematical proof which states why but I will not be expanding on it here, I will however …

Zeller Congruence (The Program)
Now that we know that the algorithm works we can know build a solution We will start by adding code to perform the calculation for this we will need to import the Python math module so that we can use the built in floor function. We will also have to take into account the months …

Zeller Pascal
It was my birthday this week so I got to thinking about one of my old Pascal Programs which was a program that used Zellers Algorithm or Congruence to calculate the day of the week from a given date. In this post all I wanted was to share my old Pascal program. In my next …

Prime Numbers
Anyone that has studied secondary school mathematics knows what a prime number is but just to recap the definition of a prime number is any number which is only divisible by 1 and itself. 1 is however not a prime number as it is only divisible by itself, and other than 2 all prime numbers …

Is Odd? or is Even?
In my last post I wrote a program to print the Collatz Conjecture for a particular number. In this program I had to check if the number is odd or not(even). For my next program I will need to do this check again so I have decided to write a very short function to check …

Collatz Conjecture (The Code)
In the This program just returns the value for a single value so we need to wirte an extra function to get the sequence: The code above adds the values in the sequence to an array and then prints simply prints the array to the screen, running the code above produces the following output: This …
