ISO8859-1, UTF-8 and GB2312

ISO8859-1, usually called Latin-1. Latin-1 includes additional characters that are indispensable for writing all Western European languages. Gb2312 is a standard Chinese character set. But the ISO 10646 code has the following problem: the UTF-16 or Unicode is a 16-bit fixed length encoding, and there is no larger room to accommodate than the Big5 or GB2312 code.

8. Dynamic Planning (1) -- The distance between string editing and string Planning

, the editing distance from S1 to S2 is d [3, 4] = d [2, 3]. ThereforeD [I, j] = d [I-1, j] + 1In fact, this is done for S1.Delete. (+ 1 is because S2 adds "c ") 3) Replace the last character of the S1 stringModifyIs "f". In this case, S1 = "abf", S2 = "def", that is, S1 [I] = S [j, the editing distance from S1 to S2 is d [3, 3] = d [2, 2]. ThereforeD [I, j] = d [I-1

Therefore, two bytes are required. The first byte represents the last 7 bits, in addition, the highest position 1 indicates that there is a byte next to it, so it is (1) 0000010, the second
