Hi,
I am taking a string as an input from the user and it should only contain the
chars:L , M or R
I tried the folllowing in kodos but they are still not perfect:
[^A-K,^N-Q,^S-Z,^0-9]
[L][M][R]
[LRM]?L?[LRM]? etc but they do not exactly meet what I need.
For eg: LRLRLRLRLM is ok but LRLRLRNL is not as it has 'N' .like that.
regards,
SZ
The string may or may not have all the three chars.
