God, is there any point in asking for a generalized solution in C#?
It would be appropriate to operate on a char array, and the examples emphasize this.

Having hard time understanding C# testcases.
Some of random test goes with input: {"excavate", "east", "strike", "transport" } which is easilly can be joined:

strikE + ExcavatE + EasT + Transport

But we excpect false for this case. What do I understand wrong with this Kata?

Do i get this kata wrong?

Faced this input array in a random testcase for C#:
"mov z 142", "mov c 1", "jnz c 2", "jnz z 2", "jnz a -2", "inc c", "inc c", "inc c", "inc c", "inc z", "dec c", "inc z", "dec c", "dec c", "dec c".

Do "jnz c 2" and "jnz a -2" create an infinite loop here?

Loved this, tried to make my solution closer to OOP, it was great practive.

Thanks to the author of this kata for helping me learn the rules of poker once and for all.
