The Bus Card

문제

You are going to purchase a bus card. It's a refillable card that cash can be deposited into, and then used to ride the bus until you are out of money. You know that you're planning to travel for $KK$ Swedish crowns (SEK). Charging the card takes some time since you can only charge it with $100100$, $200200$ or $500500$ SEK at a time.

At the moment you are in a hurry, so you want to make as few transactions as possible, but never insert more money than necessary. If you are to travel for $800800$ SEK, this means you should load it with $500500$, then $200200$, and then $100100$ SEK. On the other hand, if you are traveling for $850850$ SEK you should load it first with $500500$, and then $200200$ SEK twice. $5050$ SEK will be wasted, but it's still the best alternative.

Compute the minimum number of transactions necessary.
