Unable to understand the question

Please help me to understand this question.

Hello @zanj0,

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 in the following combinations :

dg, eg, fg
dh, eh, fh
di, ei, fi

Corresponding strings are output.

  1. vidhi contains dh
  2. divyam contains di
  3. sneha contains eh

Hope, this would help.
Give a like, if you are satisfied.
