Hello! C#, it seems that Anastasia and Elizabeth Corber have the same phone number but expected answer is all about Elizabeth Corber... Is it an issue or I dont understand the concept? (-:

I think your definition is incorrect, for example:
B I T
I C E
T E N

Yes, in the upper solution a garbage collector should remove 6 strings. Very bad if it is broken (-: But regular expressions are effective so I think it is compensated.

Ah, no rotations...
thanks, sorry for troubling:)

Hello! There is a random test: comb1 = #.#..#, comb2 = "#..#...###".
Expected answer is 11 but I think the correct one is 10:

"# . . # . . . # # #"
"  # . . # . #"

I really enjoyed this kata, thank you! But it still feels like there are not enough tests, my solution sometimes passes 10 checks in a row, but it is buggy all the same...
