I. Comparison of languages

In the previous article--js comparison version number (a), the author uses JS to use its own method complex processing the next only a pair of string version number comparison. Why is it complicated, because it does not apply to a bunch of version number comparisons, need more code, then how to solve it?In fact,JS has been packaged for us sorting function sort (), can be a good convenience to solve the stri
The function of comparing version number is often needed in the system of the client, but comparing the version number can not use the method of CompareTo in the way of the string comparison completely;This requires that we summarize the general rules of the version number, design a comparison algorithm and encapsulate it as a common method to use:Usually version number such as: 1.3.20.8,6.82.20160101,8.5A/
The difference between the Equals method used by string and = =The difference between the Equals method and = = First you know that string can be used as an object or as a base type. This refers to use as a basic type only refers to the use of methods, such as String s = "Hello", it is used as a primitive type int, such as int i = 1, and as an object to use, it means to create a new object by using the new keyword, such as String s = new String ("Hello"). But its internal action actually create
Sort : Sorts a sequence of objects according to a keyword;stability : Suppose A was originally in front of B. And a=b, after sort a is still in front of B;For example: Insert sort, bubble sort, merge sort, count sort, base sort, bucket sort instability: Suppose A was originally in front of B. and A=b. After sorting a may appear behind today's B.For example: Hill sort , high-speed sort, select Sort, heap sort internal sorting : memory that does not occupy extra memory or consumes constant;For ex
