Youku has a unique ID for each video. This ID can be obtained when you view the source file on the page,The following uses videoid = 4579646 as an example. 1. After the flvplayer load is complete, it will request the playback list of this ID from

1.1024! How many zeros are there at the end? The number of 0 at the end is determined by the number of factors 2 and 5 in the multiplication. Obviously, the number of factor 2 in multiplication is greater than 5, so we only need to count the number

Sometimes we want to generate random deep colors to meet the actual needs, such as: Color QR code, in order to make the mobile phone and QR code identification devices can correctly identify, must use a deeper color. As shown in: So how to
