Problem with findOptimalCoins function. It seems like division its not working, i thing hero is going always for the most value coin, ignoring distance.
@Kuan-Thum you might try changing out the inner while loop for a “if” statement. Also check the glasses you are wearing to ensure you can see far enough.
You could also use console.log(datacoin + " " + coin.value + " " + distance); to output each value looked at to the browser console.
