The winner of the CodeFu 2011 Round 2 is Predrag Gruevski

Congratulations to obi1kenobi who solved 4 problems in 1 hour 3 minutes.

The winner of the first iPod is Predrag Gruevski

The winner of the second iPod is Biljana Nikolovska

The calculation for the random iPod touch is ((11 * 2 + 22 * 5 + 36 * 8 + 45 * 11 + 48 * 13) mod 92) + 2 = 69
69 = MatMar = Biljana Nikolovska

In order to be transparent with the choice, the following algorithm will be used:

• 5 numbers will be taken from the Euro Millions Lottery 22th of April draw
• You can see the numbers here
• Those 5 numbers will be sorted
• Then multiplied with the following factors: 2 for the smallest number, 5, 8, 11 and 13 for the biggest number, and then a total sum calculated
• Note: The factors: 2, 5, 8, 11, 13 are chosen so that there is a smallest deviation among all possibilities, i.e. all positions have the same (or very close) possibility for being a winner
• The total sum will be cut modulo 92 and then added 2 (to get a range of 2-93, these are the competitors eligible for the prize)
• Example
  Lottery numbers from the last week were 4, 8, 21, 35, 45
  4 * 2 + 8 * 5 + 21 * 8 + 35 * 11 + 45 * 13 = 1186
  1186 % 92 + 2 = 84 This means the person with number 84 (this is still an example) would receive the random iPod

The position numbers are:
