下图是其中一个泛型模板比较函数,位于头文件stl_function.h中。 以下是全部代码样例(代码来自http://blog.csdn.net/aastoneaa/article/details/8471722): 代码语言:javascript 代码运行次数:0 运行 AI代码解释 1 //本程序为sort排序实现,方法一:重载运算符 方法二:全局的比较函数 方法三:函数对象 2 //参考http...
alphabetical order, or any other property that has a defined order. The efficiency of a sorting algorithm is typically measured in terms of its time complexity, which is a measure of the amount of time it takes to sort a list as a function of the...
A student's record consists of his or her distinct ID (a 6-digit number), name (a string with no more than 8 characters without space), and grade (an integer between 0 and 100, inclusive). Output Specification: For each test case, output the sorting result in N lines. That is, if...
java中Collections.sort()函数的用法 第一种是list中的对象实现Comparable接口,如下:/***根据order对User排序*/publicclassUserimplementsComparable<User>{privateStringname;privateIntegerorder;publicStringgetName(){returnname;}publicvoidsetName(Stringname){this.name=name;}publicIntegergetOrder(){returnorder;}...
function compareLength(a, b) { return a.length - b.length; } let words = ["apple", "banana", "cherry", "date"]; words.sort(compareLength); console.log(words); // 输出 ["date", "apple", "cherry", "banana"] 对象排序问题:如果要对包含对象的数组进行排序,需要特别注意对象属性的比较...
