Understood the logic but the code. Like how the char array is a 2-d array.
Problem with the code part
Not able to dry run it from printSpellings(n / 10)
hello @udatta
note : n/10 will remove last digit from the number.
so if n is 1234 then n/10 = 123
first we made call for 2048 which will call -> 204 which will call -> 20 which will call -> 2 which will call 0.
0 is base case so control will return back to 2 and 2 will get printed and control returned to 20 so on.
I got the dry run, but how the char array is a 2-d array.
it is for storing words.
the words are stored something like this->
thats why we need 2d array.
I did not know this, form where can I study this thing.
each string is a char array, so to store multiple string , u need to 2d array.
where each row will store one string.
Thank you, got it. It is an useful info.
