David Verrelli submitted a Comment to Problem 42362. Was ist denn los? Completely agree with Jihye Sofia Seo. Have to wonder what clutching at points by 'solving' such a spam 'problem' would do for a reputation?

David Verrelli submitted a Comment to Problem 44691. Comparison of floating-point numbers (singles) Oops. I just noticed that I forgot to rename the function from "compareDoubles" (used in Problem 44690) to "compareSingles". Unfortunately I cannot make the fix now without breaking the two successful submissions. Sorry about any confusion. —DIV

David Verrelli submitted a Comment to Problem 44383. Code breaker, Part III: Operation Xiangliu Hello, Jean-Marie Sainthillier. Thanks for your feedback. Regarding Ex. 1, the key information is given in a preceding paragraph about the general calculation of 'certitude', which states: "[...] accounting for [...] of the characters (excluding spaces)". I excluded spaces because there are none in the 'dictionary', so they would skew the results. E.g. if the phrase "They didn't understand" were padded with one hundred spaces before encoding, then we would always get a low 'certitude' if spaces weren't excluded (viz. 28%), suggesting only low–moderate confidence in the decryption, despite decoding half of the matchable characters, which should have given us high confidence (viz. 100%) given the small size of our 'dictionary'. Arguably punctuation could have been excluded too, but I opted to _include_ punctuation, not least because apostrophes do occur in the 'dictionary'. That is why there are 8 matched characters in Ex. 2: the apostrophe is counted (in _'s_). In a bigger 'dictionary', hyphens and full stops could also occur. Some punctuation, such as commas and semicolons, would perhaps never occur in any practical 'dictionary', but their effect on the 'certitude' is relatively small, and segregating punctuation according to function is beyond the present scope!! —DIV

David Verrelli submitted a Comment to Solution 1574281 This submission has evidently been copied from 'somewhere', because it is _identical_ to Solution 1499384 (submitted on 21 Apr 2018 by J. S. Kowontan). It would be good professional practice to _at least_ acknowledge the source. Moreover I don't see the point of submitting a verbatim copy of somebody else's solution; it does not bring any credit. —DIV
