I always have this thought. I’m doing it in Rust, so I check if there are negative numbers: if not, use usize. But I’m always terrified there will be an overflow somewhere.
If I were using Kotlin or Java, I might always use BigInteger just out of fear.
That’s a very interesting thought! I was thinking of writing my own Rust data type that would automatically upgrade to big integer, similarly to the int type in Python.

I am doing AOC in Kotlin. Longs are fine. I haven’t encountered a puzzle that required ULong or BigInteger.
