[2739] Total Distance Traveled

 I don't know what am I doing ......

原來其實是數學嗎！！！用算的就好嗎！！！一行就可以解決嗎！！！可惡啊XD

int distanceTraveled(int mainTank, int additionalTank){

int count = 0;

while (mainTank >=5)

{

mainTank -=5;

count+=5;

if (additionalTank >=1)

{

additionalTank--;

mainTank++;

}

}

count += mainTank;

return count*10;

}
