or, we can see that the maximum 16 bits are all 1.
For the fifth time, we move another 16 bits. Now all the bits below the highest bits are 1, in the form of 11... 111.
Finally, we add one to this value and obtain the next M power of n that conforms to 2.
Here, I found that I don't have to worry about it. First, I should judge whether this number is a power of 2

In the theory of compilers and ages finite state machines, also known as finite automata are widely used. Deterministic finite automation (DFA) is an ordered set
Where Σ is the finite set called input alphabet, U is
The Fibonacci Sequence, also known as the Golden series. In mathematics, the Fibonacci series are defined as follows by recursive Methods: F0 = 0, F1 = 1, Fn = F (n-1) + F (n-2) (n> = 2, in modern physics, quasi-crystal structure, chemistry, and other fields, the Fibonacci series are directly applied. Now, from an algorithm perspective, recursive and non-recursiv

important thing are that it must be C Onnected by a cyclic chain which means the color of pearls is cyclic connected from the left to right. And the cyclic count must is more than one. If you connect the leftmost pearl and the rightmost pearl of such chain, you can make a charmbracelet. Just like the pictrue below, this charmbracelet ' s cycle was 9 and its cyclic count is 2:
Now CC have brought in some ordinary bracelet chains, he wants to buy

Given an integer n, determine if it is a power of 2.
Idea: 2,4,8,16,32 .... are 2 of the power of n times
Conversions to binary are:

These numbers minus 1 after the bitwise and with themselves, if the result is 0, indicating that the number is 2

Because the carrier Frequency FC is a floating-point value, compared with the shaping type, it is not good for the transmission of the interface, so at the time of the protocol formulation, the carrier frequency point is used to represent the corresponding carrier frequencies FC.Carrier frequency Point , also known as EARFCN, the full name is E-utra Absolute Radio Frequency channelnumber, absolute wireless frequency channel numbers, using 16bit representation, The range is
