I have given all computer science genii a challenge. It is so impossible it is possible. You have to write codes that can do the following things:

*(a)* Be able to print the Riemann zeta function of any number.

*(b)* Be able to print off the first 10000 primes without using the Sieve of Eratosthenes

*(c)* **(extension)** Be able to print numbers in exact values for *(a)*. *e.g.* \(\pi/6\)

You can write in any language. Special prize for the winner, which will be said after the challenge has been completed.

(b)in python.EDITHere is a straight forward way of generating primes without a sieve.For each \(N\),check if any of the primes \(< \sqrt{N}\) you previously generated divide it. If they do not,then it is a prime and you can add it to the list of primes and print it out.

Another way of solving this problem is by going through each number and then use a very fast primality testing algorithm such as Miller Rabin to check for primality.

In Java:

(a), (b) and (c) using Mathematica (and I think I could solve them using Sage too).

Anyway, do not take this solution into consideration (as if you would), because it is ridiculously unfair with who is using Python, C, C#, Java, Haskell, ... to solve it.

Minor typo - in (c) it has to be \(\pi^2/6\) – Bogdan Simeonov · 2 years, 6 months ago

When I said exact values, if it has infinite digits like \(\pi\), it shows it as the string value assigned to pi. If it has lots o digits, give it in the form of an equation.Log in to reply
