Re: Sixth Contest of Newbies

Why guess 26 in the first case? The distance between 1 and 26 is the SAME as that between 36 and 26, so it is rejected after first two guesses.

Re: Sixth Contest of Newbies

About promoting: You can also post the link in TopCoder Forums. It'd be best if you do that 2/3 days before the start of the contest.
Hi thanks for your support!!

I don't have a TopCoder account, so... :-(

Re: 11608 - No Problem

I didn't run your code, but I see a very suspicious line:

Code: Select all

                cout << "No Problem. :(" << endl;
Any mistake here? :-D

Re: 11566 - Let's Yum Cha!

Problem, indeed, has quite a tricky statement :) I got AC, but I still do not understand about "(to within one dollar)" :) :roll: Oh for that part, I just copied from the problem statement of 10137 - The Trip ...

Re: 11568 - Pincer Attack!!

Hi, 1) Does bumping into mean robot and person cannot be in *adjacent" squares? Or just that they cannot be in same square? 2) Can robots see through each other? 3) What's wrong with NNWXNWWSW for my 3rd example? why a longer path is required? I simulate this and it looks perfectly fine to me. Thank...

For example, 1000 = 324 + 676 = 18*18 + 26*26.

Ha, so after two years I look at this problem description again and solve it within 20 minutes! :)
Cho wrote:Your A[a][c] will always be equal to A[0][b-a][c-a]. Thus you can reduce one dimension.
