I got two solutions for http://codeforces.net/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!
