与less相对的还有greater,都是STL里面的一个函数对象,那么什么是函数对象呢? 函数对象:即调用操作符的类,其对象常称为函数对象(function object),它们是行为类似函数的对象。表现出一个函数的特征,就是通过“对象名+(参数列表)”的方式使用一个 类,其实质是对operator()操作符的重载。 具体的例子可以去看另一篇...

You are not suppose to use the library's sort function for this problem. click to show follow up. Follow up: A rather straight forward solution is a two-pass algorithm using counting sort. First, iterate the array counting number of 0's, 1's, and 2's, then overwrite array with total...

Related to the third param of function “sort“ & Lambda of Cpp1.前置题目:1331.数组序号转换 1408. 数组中的字符串匹配1.1.两道简单题,但分别对应了,两种不同的情况,即引出:(单次排序后通过不改变原数组顺序得到其角标按照数组排序规律的数组)与lambda表达式的引出。
cpp-sort provides a full set of sorting-related features. Here are the main building blocks of the library: Every sorting algorithm exists as a function object called a sorter Sorters can be wrapped in sorter adapters to augment their behaviour The library provides a sorter facade to easily bu...
