Can you please explain me this problem.?
Smart Keypad-Advanced
Hey @CODER_JATIN
Relate this problem to your mobile’s keypad.
If you have to search the name/contact of any particular person, then you can directly search on the keypad as:
2 corresponds to letters a, b, c
3 corresponds to letters d, e, f
4 to g, h, i
so on… till 9
So, you have given a vector of names/ strings as specified in the question.
Now, the user will enter a string of digits.
Example : 34
34 will result into combinations :
dg eg fg
dh eh fh
di ei fi
Corresponding strings are output.
vidhi contains dh
divyam contains di
sneha contains eh
Will do in some time 
Hey @CODER_JATIN
Yes its correct
Just telling you one more approach
replace characters of searchIn by nos
like eab=322
After doing that search the given no in strings if present print it.
This is better approach without recursion. whos complexity is O(size of searchin*lengthof string)
Marking this as resolved if u have any other doubt regarding the same feel free to message me personally
