Here is the link for the problem:(http://www.spoj.com/problems/HISTOGRA/).
Here is my solution:(http://ideone.com/6SkfuH).
The code is giving wrong output for the example mentioned in the
solution link.The right answer for that test case is 283960245.
I tried to debug my code and I think that the stack is not popping the value at
i=2.I maybe wrong here,I am just not sure.
Your help will be appreciated.
