zero or positive number depending on whether the first argument is considered smaller than, equal to, or larger than the second argument: cmp=lambda x,y: cmp(x.lower(), y.lower()). The default value is None.
sort(first_pointer, first_pointer + n, cmp) // 该函数可以给数组,或者链表list、向量排序。 // 参数1:数组的首地址,一般写上数组名就可以,因为数组名是一个指针常量。 // 参数2:首地址加上数组的长度 n(代表尾地址的下一地址)。 // 参数3:默认不填按数组升序排序。 1. 2. 3. 4. 5. 6. 2、...

set是一个集合,内部的元素不会重复,同时它会自动进行排序,也是从小到大 而且set的insert方法没有insert(a,cmp)这种重载,所以如果要把结构体插入set中,我们就要重载’<'运算符。 set方法在插入的时候也是从小到大的,那么我们重载一下<运算符让它从大到小排序 #include<iostream> #include<vector> #include<set> ...
sort(s.first,s.end,cmp) //按照cmp方法,对str从first,到end,开始排序,cmp可自定义 //该函数需要包含<algorithm>,许多对象都可以使用 不知道大家注意到没,有些函数 容器可以用,string可以用,下标可以用,迭代器可以用。这是因为string也是一种容器,下标也是一种迭代器,string用下标更方便,并且在,string中,表...
