Idea: Mathematics + tabulationAnalysis:1. The traditional Joseph question is given n people and m. The current person is kicked out every m times and the number of the person left behind2. The first k are good people, and the last k are bad people.

It is easy to understand. It provides a string with a maximum of 2000 and q queries. Each time you ask how many different strings are in the [l, r] interval. (In order to unify the interpretation of this paper, the sa array value here is from 1 to n,

A large number is a number that cannot be expressed by the Data Type in the algorithm language. The number of digits exceeds the range that can be expressed by the maximum data type. Therefore, when dealing with large numbers, you must first

There is nothing to say about this question. Enumerate the status of 2 ^ 16 directly, use 1 to get this one, and 0 to indicate not to take it. Each time you determine whether this can be taken. [Cpp] view plaincopyprint?# Include # Include # Include
