[Andrei-Constantin-Programmer]

Create a toolkit with generic implementations of various data types and algorithms useful for AoC.

Implement mathematical formulas that are common and useful:

• Cramer's Rule (generalised)
• GCD (+ Extended)
• LCM
• Distance (Manhattan, Euclidean)
• Permutations of an enumerable
• Combinations of an enumerable
• factorise number into primes
