C++ Lists
Lists are sequences of elements stored in a linked list. Compared to vectors, they allow fast insertions and deletions, but slower random access.
Display all entries for C++ Lists on one page, or view entries individually:
| List constructors |
create lists and initialize them with some data |
| List operators |
assign and compare lists |
| assign |
assign elements to a list |
| back |
returns a reference to last element of a list |
| begin |
returns an iterator to the beginning of the list |
| clear |
removes all elements from the list |
| empty |
true if the list has no elements |
| end |
returns an iterator just past the last element of a list |
| erase |
removes elements from a list |
| front |
returns a reference to the first element of a list |
| insert |
inserts elements into the list |
| max_size |
returns the maximum number of elements that the list can hold |
| merge |
merge two lists |
| pop_back |
removes the last element of a list |
| pop_front |
removes the first element of the list |
| push_back |
add an element to the end of the list |
| push_front |
add an element to the front of the list |
| rbegin |
returns a reverse_iterator to the end of the list |
| remove |
removes elements from a list |
| remove_if |
removes elements conditionally |
| rend |
returns a reverse_iterator to the beginning of the list |
| resize |
change the size of the list |
| reverse |
reverse the list |
| size |
returns the number of items in the list |
| sort |
sorts a list into ascending order |
| splice |
merge two lists in constant time |
| swap |
swap the contents of this list with another |
| unique |
removes consecutive duplicate elements |
要注意的是list不提随机的迭代器，迭代器是个双向的，非连续存储，而且是个环状链表在尾端是个未初始化节点
空判断：begin==end;
clear remove unique(把相同元素移出，留一个先sort) insert(插入两种方式)
只能使用成员函数 sort，不能使用 算法 sort(他只接受random iterator)
