題目：
有100個(gè)蘿卜,一只兔子邊背邊吃,走一米吃一個(gè),走到家剩下多少蘿卜,(到家一共50米，兔子每次只能背50個(gè))。
假設(shè)：
兔子行動(dòng)距離是離散的，即最小行動(dòng)單位是1米。
代碼實(shí)現(xiàn)：
package CarrotAndRabbit;
public class CarrotAndRabbitForDiscrete {
privateintcarrots= 0;
privateintdistance= 0;
privateintcapacity= 0;
privateintcarrots_rest= 0;
privateintdistance_rest= 0;

}
