See a macro: # define pad_align (x, mask) (x + mask )&~ Mask)   First, you must understand the alignment operation, that is, when the number of digits is not multiple of Y, the last y is used to complete. For example, 12 is not a multiple of 8. If

The input of the program has a buffer, that is, the input buffer. The input process is like this. When a keyboard input ends, the input data is stored in the input buffer, and the CIN function directly retrieves data from the input buffer. Because

The brain is exhausted! The question is very simple, that is, to determine whether an undirected graph has a single ring. Method: DFS will dye each vertex, and check whether there are any vertices that haven't been stained. If so, no. Otherwise,
