Directly simulating the Joseph ring is N ^ 2. Moreover, the distance and direction of each movement of this question are uncertain. We can only simulate it. If we speed up searching and moving,You can increase the speed and use the line segment tree

Everyone should know the difference between I ++ and ++ I. The former uses the I value first and then increases by 1, while the latter increases by 1 and then uses the I value.But what is better about I ++ and ++ I? We will use a program to compare:[

Statement: the introduction of smart pointers in C ++ makes developers take up the peak in the fight against memory. However, nothing is perfect, and the circular reference defect of smart pointers will still lead to memory leakage. This article
