Re: 11101 - Mall Mania

wow! thanks for such idea about combining two integers... I'll try ! I optimized my JAVA code and got AC in 1.084 sec. I used BufferedReader and BufferedWriter. A faster way to combine two integers is to use shift and bitwise and. I kept the distance in it's own 2-D array and placed x and y into the...

I took 1997 because it doesnt matter at all... I have just tested and had all the time TLE. But for sure this P...

Re: 908-Re-connecting Computer Sites

Nothing wrong, but we should remember that second line (aka MST of K+M edges) should be min(cost_before, cost_after).
Shafaet_du wrote:Whats wrong with problem description? just add the costs of first N-1 inputs,and thats the first output. find MST of last K+M inputs,thats the 2nd output.
