sushiman-prime-numbers-challenge

Some Brazilian Federal University algorithm challenge - I made the Unix Way with PHP

Problem description, if I remember well:

• there is a sushiman who likes a lot prime numbers
• he would like a program to generate all prime numbers with a fixed length
• for example: 4 - it will generate all prime numbers from 1000 to 9999

I made this solution using PHP + Unix Philosophies/Rules

TODO

• handle $argv with getopt(...)
• handle input errors like strings or non positive number values
• optimize genprimes.php for algorithm to print faster
