Apologies With Programming Challenge 14

Due to a technical problem the numbers.txt file has not yet been published. This is highly unusual event and I can only apologize for this. It should appear sometime in the next few hours.

To get you started I've listed the first two numbers from the file below. To fit them in I have split each number into 4 rows of 25 characters but in the numbers.txt file they are fully 100 chars long then linefeed/carriage return on one line. so if you copy these, use backspace and join up each of the 4 lines so you have a 100 digit number.

Listing all 100 numbers here would have not made for pleasant reading! There may be leading 0s but no negative numbers or decimal points.

PS I'm halfway through the marking for Challenge 13.
