1. set元素的唯一性; 2. set默认按照从小到大排序;This type uses the default sorting criterion, which sorts the elements by using operator<. 如果你想要改变它的排序方法,需要传递额外的参数,例如: typedefset<int,greater<int> >IntSet; Note that you have to put a space between the two">"characte...
The median of M numbers is defined as the middle number after sorting them in order if M is odd or the average number of the middle 2 numbers (again after sorting) if M is even. You have an empty number list at first. Then you can add or remove some number from the list. For ea...
if(set1.value_comp() == set2.value_comp())//value_comp Returns the comparison object associated with the container cout <<"set1 and set2 have the same sorting criterion"<< endl; else cout <<"set1 and set2 have the different sorting criterion"<< endl; } voidfill(IntSet &set) { ...
std::setis an associative container that contains a sorted set of unique objects of typeKey. Sorting is done using the key comparison functionCompare. Search, removal, and insertion operations have logarithmic complexity. Sets are usually implemented asRed–black trees. ...

However, you can store them in any random order, but as soon as you retrieve them from the set, it will return the elements in a sorted fashion only. Therefore, a set contains definitions for sorting the hidden data elements from the user. The sets in C++ are implemented as Binary ...
