I got two solutions for http://codeforces.com/contest/1036/problem/F
First one: 42893786 Second one: 42893945
First solution gets MLE, though it differs from second one only in line 81. On this line in first approach I try to use precalculated values from the array, instead of calculating them anew.
Can someone explain how a person can get MLE because of trying to get a value from an array?
I tried to test perfomance of different approaches to build and use trie data structure.
I used 706D - Vasiliy's Multiset to test my versions of tries on it.
The question is: Why does approach with pointers takes 2 times more memory than one with static array? As I know, a pointer stores an address of a variable, so it shouldn't take that much memory.
Here are my submissions:
Pointer approach: 40063381
Static array approach: 40063561
Any suggestions are welcomed!
