1. map 用法详解 std map是STL的一个关联容器,它提供一对一(其中第一个可以称为关键字,每个关键字只能在map中出现一次,第二个可能称为该关键字的值)的数据处理能力,由于这个特性,它完成有可能在我们处理一对一数据的时候,在编程上提供快速通道。这里说下std map内部数据的组织,std map内部自建一颗红黑树(一种...

Kotlin has a rich API for working with strings. It contains plenty of methods for various string operations. Kotlin/Java strings are immutable, which means that all modification operations create new string instead of modifying a string in-place. ...
