华为机考-手拍球游戏

**【手拍手计算次数和总数】**游戏规则：左手和右手拍球初始数为0，首先左手第一次拍球数1下，右手拍球1下，接下来左手在拍球时是上一次左手+上一次右手的总和，右手也是上一次左手+上一次右手拍球的总和，最后拍球总数必须等于输入的拍球总和，并按规定输出。

现给定一个拍球总数，和最后输出时要打印的哪只手拍过的所有次数。每超过10 个元素，请换行输出。

输入描述：

输入为一行，拍球总数+最后打印某只手拍球的所有数量，1<= 拍球总数<=5000

输出描述：

某只手的拍的次数+某只手的拍球的所有数量

实例1：

输入：

150,left hand

输出：

now is 11 times by left hand

1 2 5 13 34 7

实例2：

输入：

100,right hand

输出：

now is 10 times by right hand

1 3 8 21 12
