+You have only $1 left at the start of the week. You have been given an opportunity to make it $200. The rule is simple with every move you can either double what you have or add another $1. Write a script to help you get $200 with the smallest number of moves.

+Doubling the value makes it faster than adding 1. The decision: dividing 200 back until an odd number comes, then substract 1.
