I would like to discuss the problem CodeChef: Practical coding for everyone
in Contest Page | CodeChef ,as the event is over
( Basically i would like to find out unique test cases where my code fails)
As soon as i saw the problem
I came up with an approach of determing the right solution by
Take the first phone number (N1) then then check if phone number 2 (N2)
if any digit of N2 exists in N1 connect them
if not then send them for deletion
Deletion>
3 steps
take a number and check more of it exists
yes ( more numbers exists) > check if they are only at concurrent positions ( left and right both)
yes concurrent
delete all
not concurrent
ignore for now and move to next number
no ( no extra exists)> delete it and increase the cost
My apporach works perfectly for the provided test cases
So is my solution CodeChef: Practical coding for everyone
but its not the right solution
So I am eger to listen to your approach or test cases where i may go wrong
thanks for giving me your precious time in reading this <3
