I have noticed that the number of solvers does not increase a lot for the CODY problem: Problem 24. Function Iterator
This problem is very interesting but not so easy to solve. This Trendy will confirm it .
Note : correct solutions can be given by the same CODY player. For example there are are 120 correct solutions for 92 CODY players (=solvers) at 07-June-2012.
