How to make BigInteger?

Question

Programming

We were asked to create a data type that would take values ​​greater than n^64 i.e. greater than long. I'm not asking you to do the task for me, just give me a hint what to do in general?

Answer 1

We need to create a class that will have methods for manipulating numbers with long arithmetic, i.e. sum, product, etc. Mostly done based on an array.

Answer 2

You can represent a number as a string, or as a set of "numbers" in base, say 1'000'000'000, stored in an array. After choosing a representation, you need to write operations to work with it (addition, subtraction, division, multiplication, etc.), then arrange it all in a class with overloaded operations.

Answer 3

Everything has already been stolen before us
