I. JAVA bit Operators
Bitwise operators are not common in actual work, but they are always very fond of these bitwise operations.Therefore, this section provides operation examples for each operator to help you understand its specific meaning.Finally, if you are interested, you can skip this chapter. Let's take a look.1. Binary Expression of an integer
Bitwise operations are binary, but we usually use decimal, for example,

This topic first needs to traverse all vertices, add the points that can be reached for the first time to the SPFA queue, and set the values of d [] and step, the other d [I] And step [I] are initialized to INF. Then, the shortest and the shortest steps of each point are obtained, and all points are scanned, perform further processing on the points that can jump out of the lake.

Back to this question, in theory, we need 10 mice to find the hidden poison.
Specifically, what should we do? That is, we need to find an algorithm. And can this algorithm only use 10 mice to find the poison in the 1000 formula?
If there is a mouse, we can make it drink half of the potion. Its Life and Death determine the half of the poison.
For example, n = 8.
