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?
In C++, this is normally due to an assert statement in C++ not returning true, but some STL elements can generate this if they try to store too much memory.
If I erase the assert statement it still does not work.
As I told you, memory consumption by arrays/STL containers are the same in both of my solutions. It is only line 81 that matters where I try to get value from j-th elemnt of the array.
I think that compiler can decrease the size of an array or remove it completely, if it understands that it will not be used.
It is not the case here, because in my second 42893945 solution I both multiply the elements of the array and push_back them into the vector, so the array is actively used, but there is no MLE.
