Can you pls explain the question
Smart Kepad-advanced
Hi @Tushar-Goel-1587999611286693 first of all, you need to look at the keypad of a phone.
Now, if you press 3, d e f you can choose either of these characters. similarly by pressing 4, g h i can be generated.
By pressing 3 4, you can reference to
dg dh di eg eh ei fg fg fi
Now, the question asks you to return all those strings from the list, in which these combinations are present. So basically you have to search for these substrings in all the strings of the given list and return the strings in which any of the substring is present. For 3 4
In vidhi, dh is present.
In divyam, di is present.
In sneha, eh is present.
Hence you return these strings as the answer.
Is it clear now?
yes, thanks a lot for the help
