@Stefan, 4+4+16+4+4+28+4+4 = 68. You don't double it again when it's next to another 2.
-
shouldn't the 3rd Test Input be true too? 3 (3*1) + 33 (3*11) + 333 (3*111) = 369
-
@Florian, you need to select the correct change exactly. 369 is not equal to 365, and there's no way to get 365 with those coins.
-
I have a solution but I think there is a better way to do it. Is there a solution that we can see?
-
@Patrick Lu, I added a featured answer, see also the Learneroo blog.
-
"The Prince will initially start with power P." It is not given in itput. What its value?
-
@Egor, he will start with the power of the first city he visits. Sorry for the confusion.
-
The first line of input contains the number of test cases... kind of matters...
-
Hmm... I pass the test input but not contest input... possibly something wrong with this problem?
-
Sorry, the challenge has been clarified, see above. Next time you're hired as reviewers!
-
So wait, can he start from only the top-left city at (0, 0)? Or could he start at any city on the left side?
-
@James, he can start any city on the left side, as shown in the picture on top.
-
Hint: Add before, then add the 3.
-
Final Hint: Note the first letter, and with more work the last and middle.
-
Thanks for the hint! I won't be sleeping tonight :P
