How do you find the interval to search next? JP. Sorry for confusing you, I wrote that "inc = 1" means 1 degree ( PI/180 ), not 1. for the interval, I choice a middle point, and add/sub a range to form the new one. In the begining, mid = PI/4.0, range = PI/4.0, interval will be ( 0, PI/2.0 ) for ea...

Thank you for your reply.
I have changed 1000 into 2000,but still got Wrong Answer. :(
Do you think my algorithm is OK?
mm... you should treat capital one and lowercase letter as different

It means that if( word[0][j] != temp[j] ) diff++

Hello, hujialie

try to declare more large, such as word[2000][2000]

Hello, LA-Z-BOy

the case you give will not happen.
you can read the problem description one more time.

Thanks for your answer. Sorry :oops: I got mixed up with the inputs. I add two more for cheking a possible overflow, they are: INPUT: 1000000000 10000000001 OUTPUT: 400000000 1600000000 second one 9897840000 10000000001 = 101 x 3541 x 27961 Actually, the problem describes that n <= 1000000000, so i...

I've thinked a lot trying to find a way to do this problem without caring about the number of words, but I couldn't find any. I coded with mallocs ... no problems with that, and I made a dfs to find the solution. It's ok , but I got TLE . I optimized it with a matrix pre calculating the distances o...

Re: 10508-Word Morphing ,runtime error!

The description of this problem include: The number of words are unlimited! But I don't know how many words there are in one case at most. One method, you can use malloc, because first line of each case will tell you how many words and how long of each word. But, since the problem descript that "Th...

10084 - Hotter Colder

I just wonder that if 'Same' occurs ...how to express area ? 0.00 ?

and after 'Same' ... all cases should be 0.00 ... right ?

plz.. give me more test case, thx :)

Re: thank you~~~

The largest rectangle is simply infinitely large. I think your proposition need some more definitions. Maybe you want to put the constraints on the rectangle that should have at least a certain number of points on the boundary or something else...I don't know hmm...only one constrain ... fit tightl...

thank Ivan Golubev and Adrian Kuegel... I starts form theta = 0, inc = 1 to searching for the smallest rectangle. Then decreasing inc to inc/10, searching in smaller interval... repeat ...10 times ... WA ... 11 times ... AC :) thank you all .... and If I wanna search the "largest" rectangle... can I...

is there always one side of input polygon be the same side of the smallest rectangle ? I'm not sure about this. My accepted solution computes convex hull and then rotates it from 0 to pi/2 to find smallest possible rectangle. mm.. I rotate it from -PI~PI using rotation matrix, inc theta by PI/1800 ...
