Hey @gargshivam2001
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
