ctx$\_$append

void ctx$\_$append$($const char ident$[],$ int val, char ctx$\_$k$[][$MAX$\_$IDENT$\_$LEN$],$ int ctx$\_$v$[],$ unsigned int size$)$;

Binds the variable ident to the value val in the context represented by $ct{x}_{-}k$ and $ct{x}_{-}v,$ which have sizes size $.$ Raises ctx$\_$overflow if the arrays ctx$\_$k and ctx$\_$v are not large enough.

Do this by placing ident and val at the next available empty slot of ctx$\_$k and ctx$\_$v respectively.

You should implement the following recursive helper function, which will not be directly tested. Your implementation of ctx$\_$append, which does not have to be itself recursive, should call the helper function with the appropriate arguments.
