when I use an array of vectors... thereby not allocating huge ammount of memory, I get a TLE. I dont understand it. array lookup is O(1) and each vector should not be verry large. Please somebody help me in this regard. what data structure I should use. what is the basic flaw here ...

but why is it giving Runtime error (SIGSEGV 11) instead of Memory Limit Exceeded??

I just hate getting stuck.

Hello.
I am new here. I have been getting Runtime error (SIGSEGV 11) for problem 10029... http://acm.uva.es/p/v100/10029.html
Although my program runs fine on my solaris box and algorithm seems to simple. Here is my code.
TIA
