Question:Given a positive integer, check whether it has alternating bits: namely, if two adjacent bits will always have different values.Solution:Question Setting requires determining a number in the form of 101010. How can we give an algorithm with the minimum complexity?First, let's take a look at the basic tools to solve this question using python.Speaking of binary, the first thing that comes to mind is
-s file cancels the SUID permissions of the main location of the files2 . Command function:SUID: when running a program, the owner of the corresponding process is the owner of the program file itself, not the initiator; SGID: when running a program, the group of the corresponding process is the group of the program file itself, not the base group to which the initiator belongs;Sticky: in a common directory, each can create files, delete their own files, but not delete others ' files; 3 .

BitsLet's denote as the number of bits set (' 1 ' bits) in the binary representation of the non-negative integer x.You are given multiple queries consisting of pairs of integers l and R. For each query, find the X, such this l≤x≤r, and is maximum possible. If There is multiple such numbers find the smallest of them.InputThe first line contains integer n-the number of Queries (1≤n≤10000).Each of the followin
Sticky bits (stickybit), also known as sticky bits, are a flag for UNIX file system permissions. The most common usage is to set the sticky bit on the directory,Can only be set for the record, for the effectiveness of the piece. After the sticky bit is set, only the owner or root of the file in the directory can delete or movethe file. If you do not set a sticky bit for the directory, any user with the w
