如果有一个文件aaa.txt,有若干行,不知道每行中含有几个整数,要编程输出每行的整数之和,该如何实现? 由于cin>>不能辨别空格与回车的差异,因此只能用getline的方式逐行读入数据到string变量中,但在string变量中分离若干个整数还是稍显吃力.一个好的方法是用string流: #include<iostream> #include<sstream> #include<fstream> using namespace std; int main…

注意,本文不是字符串排序,是字符串数组的排序. 方法分别是: 1.低位优先键索引排序 2.高位优先建索引排序 3.Java自带排序(经过调优的归并排序) 4.冒泡排序 5.快速排序 6.三向快速排序 时间复杂度: 最慢的肯定是冒泡,O(n的平方) 最快的是快速排序,平均 O(nlogn) 低位优先,O(nW),W是字符串长度,在字符串长度较短情况下和快速排序时间应该很接近 高位优先,O(n) - O(nW) 三向快速排序,O(n) - O(nW) 本文中使用的例子是一个5757行的随机字符串数组…

一 概述 String由final修饰,是不可变类,即String对象也是不可变对象.这意味着当修改一个String对象的内容时,JVM不会改变原来的对象,而是生成一个新的String对象 主要考虑以下原因: 为了实现字符串池(提升效率) 只有当字符串是不可变的,字符串池才有可能实现.字符串池的实现可以在运行时节约很多heap空间,因为不同的字符串变量都指向池中的同一个字符串.但如果字符串是可变的,那么String interning将不能实现,因为这样的话,如果变量改变了它的值,那么其它指向这…
