I like this too, but I didn't know you could change the method signature, but your way of doing so was elegant. It effectively side-steps the whole issue.
Either it has been changed in the meantime or you just didn't read correctly the last line of the description.
And since 6m is greater than 2*2.77, the answer is true. The testcase is correct
Hey @mystery! Can you let me know what looks wrong about it? Thanks in advance!
Looks fine to me.
