Time for another summer code-challenge. Hopefully this one is a bit easier than the last one :-)
Mr. Michael was a lucky man, cause today, 20070710 (ISO standard) was his birthday!
But Michael wasn't your average lucky birthday boy. He was a Math Maniac. And on this special day, he was wondering: How many of the numbers between 0 and 1.000.000.000 contains the ciphers "20070710" (in that order) somewhere within the number?
Design a method int CountNumbers(int min, int max, int SequenceToFind); that returns the count of numbers which contains the SequenceToFind.
1st prize goes to first valid entry, 2nd prize to best performing entry.
The prizes are still "honour & mocking rights".
May the best developer win.
