Topic Link: 51nod 1264 segment intersectionIf two segments intersect, either one of the endpoints of one segment is met on another segment, or two segments are on a straight line extending across another segment. (If the point P1 is on one side of the line p3p4 and the point P2 is on the other side of the line, it is said that P1p2 crosses the line p3p4.) )Cross-multiplication can be used to determine whether the P3P1, p3p2 are in different directions in the P3P4 (CIS, counterclockwise) (line se
principle:Several check codes are added to the data, and each bits of the data is assigned to several parity groups.Set: The number of check bits is R, can represent 2^r information, one means "no error", 2^r-1 to indicate the error occurred in which one.k= 2^r–1-r information can be used to correct a data bit.2^r≥k+r+1To detect and correct a single error, while discovering two errors, the R,k should meet the following relationships: 2^r-1≥k+r (see table 3.8)How the check bit and data bits are a
when I was a product manager, the company requested 55 documents, both large and small, it was mainly because the company had to pass an international certification and there was no way to do so.
Although it is only a requirement to "understand", ten of them must be written, and four of them must be proficient (in italics ).
