#include <iostream>

/*
 *
 * 3.8 v2
 *
 * I think both while and for are viable but i will say the range for is very minimal and nice.
 * My C programmer brain feels more at home using something like a regular for / while loop with subscripts
 * But i do think the range for is nice. It might take a bit of time getting used to using ranged for loops
 * and it might take some time being able to recognise which situations it's best used but i think its a
 * great tool to have either way.
