My solutions to CodeEval.com challenges

These challenges offer a nice opportunity to solve problems not of the sort I usually experience at work. I try look for challenges where I recognise the need to use std library functions or techniques that I'm not that familiar with as a learning opportunity.

Listing of noteworthy features and the code I use that I may want to refer back to.

Standard library calls

Function	Code
std::next_permutation()	14, 48, 86
std::set_intersection()	48
std::iota()	48
std::isdigit()	108, 51
std::isblank()	51
std::copy_n()	108
std::minmax_element()	213
std::numeric_limits()	51
std::accumulate()	69
