Plan and done for June-22-2017

Stuck a little with the yesterday's problem. The reason - can't add up only those remainder's groups which don't give a divider mutually - I've set an array of 'banned' remainders and try to use it inside Array.prototype.reduce() but it seems like it's not seen inside reduce loop.

The solution for this was quite easy - I added to an array numbers and checked if an element is included with a string equivalent. Added plus sign before an element so it looked like Arr.includes(+num) and everything started to work great.
