If you do that inside the BFS you are repeating a lot of comparisons.

Thanks a lot brianfry, I missed that optimization.

I used this comparison..

Code: Select all

// check length, if not same no need to run bfs
solved

I got TLE. Can not figure out the bug.
I used BFS to find shortest path to trasnform from source to destination. If the query strings are not of same length or both are same, then just printed 0.

I got WA. Please help to find my mistake. My idea is: get a line using fgets until EOF check Capital letters, make them small letters tokenize string using strtok() by " 0123456789!@#$%^&*\()_+=-[]{}|\\:;\"\'<,>./?`~" and insert into a map as key(because it sorts itself) finally p...

Getting WA. 1. I followed http://www.regentsprep.org/Regents/math/geometry/GCG6/RCir.htm this link to find h and k. Then normalized and found r, f, g, c. 2. To aovid division by 0 I first checked if 0 == 0 then it result is 1, if denominator is 0 then result is 0, otherwise did division. Here is my ...

Got WA in this topo sort problem. I thought all possible valid outputs should be accepted. I just did a straight forward topological sort. I am not getting what to do with it. Thanks in advance. #include <iostream> using namespace std; int main ( ) { while( 1 ) { printf( "Thanks, Brianfry. AC N...

@plamplam
yeah, thats the big hint indeed, draw it down into notebook and it worked really great.

these kind of problems just waste our time why "t" is diameter ??? in image in the problem "t" is`nt diameter :D so i have some other test cases in the problem problem setter says "All these integers are less than 100" so can you solve these test cases? : -1 -2 -100 0 ...

I have a question, what should happen if there is a space right before end of line ?? My code does not get the line feed for this. I did not used "gets". At first got Wa. I read all the clarifications then Accepted. Some samples by my AC code. Input: I love you. You love me. The output wil...
