write a program that finds all the fractions (from 100 to 9999) as the image

>> No.10459981

why? do it yourself

>> No.10460006

>>10459978
The set of all fractions between 100 and 9999 is a subset of R/Q. Therefore there are uncountable many.

This is a simple application of almost matching patterns. Write it yourself. Bonus points if you go ham and use function convolutions

The natural inclination is to consider rational fractions then. Then there is a clear bijection between the naturals and the these fractions

>> No.10460538

>>10459978
Also this is a related combinatorics question
>given up to 10 numerals, how many pairs of unique naturals can I produce such that they share no common numerals

I guess there’s the added restriction that there are no repeated symbols in a single string either. Otherwise, the number would be infinite

Even if we consider all fractions, it's still not a subset of R\Q since there are rational fractions

Yep, I was wrong. Theres still uncountably many irrationals on a given interval in the reals though.

Yes, and it's irrelevant. You cannot redeem yourself now so if I were you i'd just stop posting lol.

Its in pseudo code:

Post question on 4chan;
Question ("write a program that finds all the fractions (from 100 to 9999) as the image");
Return (answer);
