Technical Field

The invention relates to the technical field of character data processing, in particular to a character sorting method, a system and a device based on JavaScript and Unicode.

Background

A sorting algorithm, i.e. one or more sets of data are reordered according to a given pattern by a specific algorithm factor. The new sequence follows a certain rule and embodies a certain rule, so that the processed data is convenient to screen and calculate, and the calculation efficiency is greatly improved. The most basic requirement for sorting is to have certain stability, that is, when two identical elements appear in a certain sequence at the same time, after a certain sorting algorithm, the relative positions of the two elements before and after sorting do not change. In other words, even two identical elements are each distinct in the ordering process and do not allow confusion.

Currently, common schemes for sorting in JavaScript platforms are bubble sorting, selection sorting, insertion sorting, and sort methods. The bubble sorting method has the disadvantages that the speed is low, the complexity in operation is O (n2), and the requirement of large array sorting cannot be met; the selection of the sorting is an unstable sorting algorithm, and the number of times of executing the comparison is too many, which easily causes unnecessary performance waste; the insertion sequence is similar to the insertion of playing cards, and once the sequence with a large order of magnitude is encountered, the operation times can increase in a geometric series manner; the sort method is a method of parsing through a browser engine, comparing and sorting are always performed with an ASCII value of a first character, and the method defaults to converting all elements into String first and then sorting, and a plurality of problems are generated when the method is directly used.

Therefore, how to realize the rapid and reasonable sequencing of character strings aiming at a large number of use scenes needing to sequence the character strings is an urgent problem to be solved.
