I am not getting what the question is asking me to do. Can you please elaborate.

Hi Vaibhav,
In this question first you have to find all the combinations you can made with the input on a keypad.
For eg: if the input is 34 the you can make following combinations:
1>dg 2>eg 3>fg
4>dh 5>eh 6>fh
7>di 8>ei 9>fi

now you have to print all the strings given in the searchIn list having any of the above 9 combinations as a substring.
