Very entertaining puzzle.
Hint to the frustrated, as I was:
This is a "noise" exclusion problem. The 1-sigma uncertainty in the time measurement is greater than the "true" time delta between foo and goo.
The test suite method is also vey well executed.
Indeed the solution is random...
since tic toc didn't give me results, I tried the cody size approach
I tried a lot of times this solution without sucess
As did I, even with 10,000 iterations in the loop. My problem was that gamma took longer than sign did, despite the test suite saying it shouldn't. After four or five tries, I had to add an ugly hack that checked if foo was gamma.
Good to know this method does occasionally work, though...
