in this ques how char values are take from the input???
and how they mad combinations???
Pleasse explain the ques
@akshatj07 Hi bro so here is my two cents for the explanation part -
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
Now this is the keypad array you have to use like this -
public static char[][] keypad = {{’ ‘}, {’.’, ‘+’, ‘@’, ‘$’}, {‘a’, ‘b’, ‘c’}, {‘d’, ‘e’, ‘f’}, {‘g’, ‘h’, ‘i’}, {‘j’, ‘k’, ‘l’}, {‘m’, ‘n’, ‘o’}, {‘p’, ‘q’, ‘r’, ‘s’}, {‘t’, ‘u’, ‘v’}, {‘w’, ‘x’, ‘y’, ‘z’}};
Bro if you have done smart keypad - 1 then it will be easy for you because just you have to search in the given array.
If you want code for reference I can give that to you, but bro try if you can do it by the hints!
Happy coding buddy!
