Rafael S.T. Vieira submitted a Comment to Problem 52654. Easy Sequences 13: Average Speed of Spaceship

Tip: This is not a classical-physic-only problem. As far as I know, the digamma function is not taught in high school.

Rafael S.T. Vieira submitted a Comment to Problem 51768. Redefine the Array if the Elements in the Array are Repeating

The exclamation mark "!" is a repeating element that should be removed from the output according to the problem's description, and n is equal to 1 (since there is no input parameter to control it). Moreover, there is no reason for d to be capitalized in the output. Please, fix the problem description or the test suite

Rafael S.T. Vieira submitted a Comment to Problem 49808. Identify eban numbers

Chris was trying to write without the letter E. He wrote "list quantity" instead of a list of values, number list, or list of quantities. It seems clear to me despite not being grammatically correct. And this is a legit problem; A006933 at OEIS.org.

The problem description is not very clear, but the sequence of keys is 1,2,3,1,2,3, ... like problem #2 of this series.
