Question: Given the N numbers of 1-N, how many subsets are there? The lcm in the set is greater than or equal to m.   We can find that the range of m is very large, and the subset of 1-N is also a lot of 2 ^ N-1. I think it would be DP, but the data

Converts a given string to a number. If the result is positive, 2147483647 is returned. If the result is negative and large,-2147483648 is returned. In addition to numbers, a string also contains spaces and other characters. Therefore, you must

1. The function is static when it is not called, and the form parameter is only a symbol. The function is executed only when it is called. It is also called before the main function assigns the real parameter to the form parameter.   2. function
