This problem is similar to http://www.mathworks.com/matlabcentral/cody/problems/1092-decimation, only this time the score will be based on how quickly you can determine which person will survive.

The sample sizes (num_prisoners) and number of prisoners killed (num_killed) will be larger than in the original problem, but other than that the problem sets are identical.

My submissions keep getting an error that they time out for all the test cases. Running tic/toc on it for case one in the Scratch Pad it takes 0.003869sec. My solution works for problem 1092. If I hard code a numeric output the test cases do not time out.
