@abhishekg,

Your are given this string input table:
string table[] = { " ", “.+@$”, “abc”, “def”, “ghi”, “jkl” , “mno”, “pqrs” , “tuv”, “wxyz” };

Here if you press 0 it will give you " ", if you press 1 it will give “.+@$” and so on.

In the output you have to print all possible string combinations for a input string string say 12.
If you press 1, possible characters are: .+@$
If you press 2, possible characters are: abc
Hence output will be combination of all the characters.
