### Re: Problem 125

It didn't take too long to figure out that the palindromes that are themselves squares are not meant to be included in the sum, but you really should include a note mentioning this explicitly, or at least change the wording of the problem. A sum with a single term is still a sum. Unnecessarily slopp...

### Re: Problem 080

I think it's ridiculously stubborn on the part of the mods to refuse to alter the wording of the question. Many people have been thrown off by the phrase 'decimal digits' which is assumed to imply the digits after the decimal point. If you insist on retaining the current formulation of the question,...

### Re: Problem 273

There's an 's' missing in 'integer' in the first line of the problem statement.

And the same missing 's' in the same word on line 4.

This is a minor nit, but we are looking for the 124th

*smallest, positive, odd*integer that doesn't divide any terms of the sequence, yes?

Any chance this can be made public?

### Re: My blog about my PE journey.

I'd read your blog if it wasn't for the inadvertent spoilers sprinkled in. Nothing specific, but I don't want any hints or ideas for how to solve problems. For anyone like-minded, beware.

### Re: Problem 345

Any chance the light green color that highlights the entries that are used in the example sum can be changed to a different color that is not so annoying to look at? Maybe something like red?

Do I understand the problem correctly? That is hard to tell from your own description. Let's restart using your own data and hk's suggestion. - First let's "encrypt" your HELLO WORLD with your encryption key 'abc'. Rotating the key for XORing each character of the message, the end result ...

### Re: Problem 059

I finally solved this one. I beseech the moderators to completely overhaul the wording of this problem, because as it is written it might as well be a 50% difficulty problem rather than the 5% at which it is currently listed. Pretty much all the difficulty of this problem lies in figuring out what t...

Can you tell me if my understanding is correct, as reflected in my previous post? A simple yes or no will suffice.kenbrooker wrote: ↑Fri May 22, 2020 6:59 pm ByAnimus, this is a key to answering your question --

### Re: Problem 059

As I understand it, each letter was given a number, and that same number is used each time the same letter appears. No, that would have been encryption via substitution and has nothing to do with the described XOR encryption. Now what exactly is a decryption key? If it is supposed to give you the v...

Typo in the first sentence of the problem statement. The word 'of' doesn't belong there.

Is there something... Evil about cleverness that I am not aware of? That needs to be "prevent"ed?! Surely you jest? Nothing wrong with cleverness, but I do think that one of the qualifications for a problem to make it to PE is that it should be a true combination of math and programming, ...

### Re: Problem 089

Some "rules" for Roman Numerals even state -- A numeral can be repeated in succession up to three times only. Allowing only four repetitions at least avoids the conflation "VIIIII" = Ten vs "X" = Ten... Just some random thoughts... True. Although allowing more than 4 w...

### Re: Problem 089

Why is this note

"Note: You can assume that all the Roman numerals in the file contain no more than four consecutive identical units."

included in the problem statement? Why can't we have more than four consecutive identical units?

Are we only considering sums that have at least two summands, as in problem 76? Please update the problem statement if yes. Thanks.
