I am taking a string as an input from the user and it should only contain the chars:L , M or RI 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.
try "[LRM]+$" (an L or an R or an M, one or more times, all the way to the end of the string).
