Hello!

I can't believe how I got stuck here, I have about ten exercises to do and this is just the first one and it is supposed to be the easiest of them. I can't even figure this one out.

So, I have the following code:

myText = 'Rome 2.7  Stockholm  3.8  Oslo 0.9    Madrid 2.8   Barcelona 12.1   Paris 9.2'
mySolution = regexp(myText,,'match')

My task is to extract only the names of the cities from "myText". What do I have to write between the two commas in the expression "regexp(myText,,'match')" to achieve this? It is likely something very obvious.

I tried the following:

myText = 'Rome 2.7  Stockholm  3.8  Oslo 0.9    Madrid 2.8   Barcelona 12.1   Paris 9.2'
mySolution = regexp(myText,[a-zA-Z],'match')

but this only separates each word when I should get the whole city names.

My brain is completely stuck, so any hint on how to solve this would perhaps get me going with the logic behind rest of the tasks too. Thank you in advance!
