Isn't it easy?
To determine whether a number N is a power of 2, you only need to check whether N & (n-1) is 0.
To find the power of 2 that is larger than it, You can first fill the highest one of it with 1 and then add 1.
The filling method can be
In MATLAB, EPS is used directly, and the default is for double-precision types.So in Microsoft's MSDN:Numeric_limits::epsilonThe function returns the difference between 1 and the smallest value greater than 1 that's representable for the data typ

Sorting Algorithm Summary (Bubble sorting, simple selection sorting, and quick sorting)
1) bubble sort bubble_sort1. PrincipleAssume that a [n] is sorted.Compare two adjacent numbers in sequence, before decimal places, before large numbers.* 1.
// Select sort by file. cpp
// The basic idea of sorting:// Assume that N pieces of data are placed in array A. Sort the N numbers in ascending order.// First, within the range from a [0] to a [n-1], the small value element is selected to exchange
