# Most compiles will safely use -O2. Some can use only -O.
|
||||
# A few compilers have broken optimizers and thus you may
|
||||
# not want anything.
|
||||
# Regarding individual entries:
|
||||
#
|
||||
# IOCCC winning entry code may not work on your system. Even with standards,
|
||||
# conditions and build environments change, especially when it comes to more
|
||||
# extreme code such you might find in an IOCCC winner. Moreover, what was
|
||||
# allowed and liked in one IOCCC contest may no longer be liked/allowed in
|
||||
# later IOCCC years.
|
||||
#
|
||||
# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
|
||||
#
|
||||
# GitHub pull requests are welcome:
|
||||
#
|
||||
# If you have a patch that might make running an entry work in modern Unix-like
|
||||
# environments, please create a GitHub pull request for the IOCCC judges to
|
||||
# consider.
|
||||
#
|
||||
# Suggestions and corrections regarding Makefiles, winning author information,
|
||||
# fixing typos in remarks, and code patches are welcome via opening a GitHub
|
||||
# issue or better yet, by creating a GitHub pull request for the IOCCC judges
|
||||
# to consider. To form a GitHub issue or GitHub pull, please visit:

This code is an nice compact example of a Modular Fast Fourier Transform.
|
||||
While its output is very specific, the internal FFT has a wide variety
|
||||
of uses.

## Judges' comments:
|

|

Can you modify this code to produce primes such as 23523*2^70000-1,
|
||||
48594^65536+1 or 6917!-1?

### Alternate code:
|
||||
|
||||
This program prints the biggest known prime number (2^6972593-1)
|
||||
in base 10. It requires a few minutes. It uses a Modular Fast
|
||||
Fourier Transform to compute this number in a reasonable amount
|
||||
of time (the usual method would take ages !).
|
||||
|
||||
The program uses >= 64 bit 'long long' type. It should run on any
|
||||
system with a gcc compiler.
