http://ww2.codechef.com/viewsolution/2106785. See this nice solution. It is AC without using any segment trees and some advanced technique

Hi the segment trees section in the top coder tutorial only explains how to initialise the tree n query for a *minimum* in a given interval … could someone pls spare few mins explaining wat changes must be made to that algorithm to fetch the maximum in the given interval … It would be really very helpful … apologies if its a silly question …

hi mkagenious. I have tried and tried but getting a wrong ans. I have also looked at others solutions, but cant find any faults in mine. Could you please help me? My submission ID : 2172602.

please some one help me in this code…http://www.codechef.com/viewsolution/2172202...giving wrong answer…cross checked many times…

Wrote the code using RMQ. Can anybody guess where did I go wrong ?

- Link to my code : http://ideone.com/lLzB7a

I am solving this problem in O(Qroot(N)) but getting WA. I dont know where the code is failing,please check it once.

here is Ideone the link.

I implemented a Python solution for this problem and it is as fast as the few Python AC ones but I got TLE. Can someone spot the issue ? http://www.codechef.com/viewsolution/2188068

Hey , I followed the first approach (finds range min query in time O(rootN)) . Upon submitting the code , I am getting Runtime Error. http://www.codechef.com/viewsolution/2185571

Total Memory Limit for this 50000 bytes.I declared two arrays of size 10000 each. So , it takes 80000 bytes [2*40000 bytes]. Is this the reason for the error ?

But, I have seen solutions using two arrays getting accepted.

I have implemented the segment tree and correct approach , it is working for basic test cases but giving WA can somebody see http://www.codechef.com/viewsolution/2276619

i m getting WA for the question http://www.codechef.com/problems/MSTICK but not able to figure out why… kindly help… my solution is

I get WA,can anyone tell me what am I doing wrong?

My submission- http://www.codechef.com/viewsolution/3339304

Hey Though I have test a lot of test cases and have considered the double part still the WA…

heres my sol: http://www.codechef.com/viewsolution/3655905 .plz help…

Can anyone please find the error.The code is working on all test cases I could find,but could not locate the error,getting WA.

Plz Help…

Hey I have used 2 segment trees for implementation. But still, I am getting wrong answer. Can’t figure out why. Could anyone please help me out? Solution : http://www.codechef.com/viewsolution/3792862

http://www.codechef.com/viewsolution/3902702 Can view my sol here. Not getting where is the prob,getting correct answer for all test cases

I am trying to solve the problem matchsticks http://www.codechef.com/problems/MSTICK

I used segment tree data structure still I get TLE with a complexity O(2N + Q4*log(N))

where O(2N) for building 2 segment trees and O(4Q*log(N)) for running 4 queries on the segment tree for each query Q.

Can somebody please correct me if I am wrong about the complexity of my algorithm or help me find out why do I get TLE ?

I would appreciate it, thanks
