已知 n 个正整数，从中选择 m 个进行与运算得到一个新的数。例如：已知 1、2、3 从中选择两个数进行与运算，可以是：1 & 2 = 01 & 3 = 12 & 3 = 2-Known positive integer n, choose the m operation carried out to get a new number. Example: Given two numbers 1,2,3 and operation can be: 1 & 2 & 3 = 01 =

有n个整数，使其前面各数顺序向后移m个位置，最后m个数变成最前面的m个数-There are n integers to move back in front of the order of the number of m-position, the last m into the top of the number of the number of m
