兔子和萝卜问题

题目：

有100个萝卜,一只兔子边背边吃,走一米吃一个,走到家剩下多少萝卜,(到家一共50米，兔子每次只能背50个)。

假设：

兔子行动距离是离散的，即最小行动单位是1米。

代码实现：

package CarrotAndRabbit;

public class CarrotAndRabbitForDiscrete {

privateintcarrots= 0;

privateintdistance= 0;

privateintcapacity= 0;

privateintcarrots_rest= 0;

privateintdistance_rest= 0;

public CarrotAndRabbitForDiscrete(intcarrots,intdistance,intcapacity) {

this.carrots=carrots;

this.distance=distance;

this.carrots_rest=carrots;

this.distance_rest=distance;

this.capacity=capacity;

}

public int results() {

while(distance_rest> 0){

this.forwardOneMeter();

}

return this.carrots_rest;

}

public void conditions(){

System.out.println("Distance: "+distance+" ,Carrots: "+carrots);

}

private void forwardOneMeter() {

intmax_num= 0;

intdiscard_carrots= 0;

if(carrots_rest%capacity> 2){

max_num=carrots_rest/capacity+ 1;

}else{

max_num=carrots_rest/capacity;

discard_carrots=carrots_rest%capacity;

}

this.carrots_rest-=discard_carrots;

if(max_num< 1) {

this.carrots_rest= 0;

this.distance_rest= 0;

}elseif(max_num== 1) {

this.carrots_rest--;

this.distance_rest--;

}else{

this.carrots_rest=this.carrots_rest- 1 - (max_num- 1) * 2;

this.distance_rest--;

}

//System.out.println(carrots_rest + ":" + distance_rest);

}

public static void main(String...strings) {

CarrotAndRabbitForDiscretecarrotAndRabbit=newCarrotAndRabbitForDiscrete(100, 50, 50);

System.out.println(carrotAndRabbit.results());

}

}
