REGEX quiz

Hi guys,please help identify the solution.

Thanks in advance


option C

after +40- you need all the digits means this will be right


Hi @Latifa

The answer would be option D


There are many hints that C is not the answer

@Latifa you can learn and prototype also directly like:


except option A all are correct

if you want to get the digits after +40

then Option D is perfect

@Anil_G @postwick @mkankatala your opinion with explanation for my understanding please

Sorry, I have no clue what they’re even asking here or what their screenshots are. It makes no sense to use RegEx for this.

@postwick The question is;
How should the regular expression be configured in the RegEx Builder to match only phone numbers starting with +40 in the format shown above?

I don’t know, I tried all of their choices and none of them actually work.

This is RegEx that actually works, of course it isn’t one of their choices.

No, as from the classes it can also match +04 and digit blocks which are different

We gave you a hint on

  • how to check in the matches what each options will do
  • using Regex101 to get explanations on patterns

when the phonenumber in the format starting with +40 and then with three blocks of -XXX (X=Digit) is to match

then you will find 1 option where all contstraints are reflected. Some cheaters:

  • look at the hypen (-)
  • look at the pattern which gives you a -XXX Block

I edited it. Look again.

However, I actually tried all of their four options and none of them worked.

Why are you asking these type of questions?

@ppr thanks for this. I am watching some videos here on regex grouping and option D comes close. I am not sure if I got it right.Am still a newbie and appreciate your challenge
