The most efficient way to implement an integer based power function pow(int, int)
... no efficient algorithms to find this optimal sequence of multiplications. From Wikipedia:
The problem of finding the shortest addition chain cannot be solved by dynamic programming, because it does not satisfy the assumption of optimal substructure. That is, it is not sufficient to decompose th...
What is the difference between const_iterator and non-const iterator in the C++ STL?
... method signatures.
Much like const and non-const, you can convert easily from non-const to const, but not the other way around:
std::vector<int> v{0};
std::vector<int>::iterator it = v.begin();
// non-const to const.
std::vector<int>::const_iterator cit = it;
// Compile time e...

So, you can use it that way :
library(purrr)
