My solutions to Project Eulers problems https://projecteuler.net/
For my solutions in Python, I typically use Visual Studio Code or more often Anaconda's Jupyter Notebook, which utilizes Python 3.
I have also uploaded some of the solutions written in Matlab.
I also try to use as many of my own functions as possible. This includes creating my own code for checking whether a number is prime (is_prime(n)) and listing all the primes below an inputted number (listofprimes(n)) instead of using python's sympy built in fucntions: isprime() and primepi(n).
2, 3, 9, 10, 39, 47, 50, and 53.
is_prime(n): checks whether a number is prime or not. TRUE or FALSE.
listofprimes(n): lists all the primes below an inputted number. Outputs a number.
factorial(n): take the factorial of the input using the factorial equation
combination(n,r): taking a combination using the equation (n, r) = n!/ (r!(n−r)!)
