Smart keypad advanced problem

#1

I have a doubt in the question and I will be rellly glad if you will be able to clear it.
If the input is of length greater than any of the strings , then what should I be printing ?
Say for example, if I give 23456789 and the longest string is of length 7, say “prateek”. What do I print in this case, since the input will not have a substring in the string prateek, all the strings formed from the input will be greater than prateek.
