【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
