python 实例练习:有n个人围成一圈,顺序排号。从第一个人开始报数(从1到3报数),凡报到3的人退出圈子,问最后留下的是原来第几号的那位。

附加: 第一个 while 循环跑的过程
k = 1 [1,2,3,4,5,6,7,8,9,10] num[0] = 1 k +=1 i += 1 ==> k = 1 i = 1 m = 0
k = 2 [1,2,3,4,5,6,7,8,9,10] num[1] = 2 k +=1 i += 1 ==> k = 2 i = 2 m = 0
k = 3 [1,2,0,4,5,6,7,8,9,10] num[2] = 3 k +=1 i += 1 ==> k = 0 i = 3 m = 1
k = 1 [1,2,0,4,5,6,7,8,9,10] num[0] = 1 k +=1 i += 1 ==> k = 1 i = 4 m = 1
k = 2 [1,2,0,4,5,6,7,8,9,10] num[1] = 2 k +=1 i += 1 ==> k = 2 i = 5 m = 1
k = 3 [1,2,0,4,5,0,7,8,9,10] num[2] = 3 k +=1 i += 1 ==> k = 0 i = 6 m = 2
k = 1 [1,2,0,4,5,0,7,8,9,10] num[0] = 1 k +=1 i += 1 ==> k = 1 i = 7 m = 2
k = 2 [1,2,0,4,5,0,7,8,9,10] num[1] = 2 k +=1 i += 1 ==> k = 2 i = 8 m = 2
k = 3 [1,2,0,4,5,0,7,8,0,10] num[2] = 3 k +=1 i += 1 ==> k = 0 i = 9 m = 3
k = 1 [1,2,0,4,5,0,7,8,9,10] num[0] = 1 k +=1 i += 1 ==> k = 1 i = 0 m = 3
k = 2 [1,2,0,4,5,0,7,8,9,10] num[0] = 1 k +=1 i += 1 ==> k = 2 i = 1 m = 3
k = 3 [1,0,0,4,5,0,7,8,9,10] num[0] = 1 k +=1 i += 1 ==> k = 0 i = 7 m = 4
.....................
循环过程写错了,希望大家能指出来,谢谢(我自己写的也有点懵)
