Dyuman, Test 5 is missing a parenthesis.
Fixed. It's always something with my test suite :')
Dyuman, Thanks for the problem. It might be good to add that what you mean by a local maximum is not only that the value is the largest value, but also that it is strictly greater than the second largest. Likewise for a local minimum.
William, thanks for the comment.
I thought the value of extrema was based on strict criteria. I stand corrected. The problem statement has been updated.
Yes, if this were a continuous function, an extremum would imply that the value was strictly the largest. In the case of a set of discrete values, though, it may be debatable whether two equally large neighbors should be considered as 2 maxima or not.
I see, thanks for the clarification!
