The reason the OP code doesn't work is that the @inp_word
array contains elements of one character each, because it gets the output of split(//,$inp_word4);
But then your logic depends on some element of @input_word
containing "na", which can never happen.
If I understand your task description correctly, I think you just need a basic regex substitution:
part there is called a "positive look-back assertion" - check that out on perlre
. It says that any "m" will be replaced by "+d" if it's preceded by "na".
