标准容器的复杂性保证是什么？

显然;-)标准容器提供某种形式的保证。

哪种类型的担保以及不同类型的容器之间到底有什么区别？

从工作的SGI页（约STL）我拿出这样的：

Container Types:
================
Container:
    Forward Container
        Reverse Container
            Random Access Container
    Sequence
        Front Insert Sequence
        Back  Insert Sequence
    Associative Container
        Simple   Associative Container
        Pair     Associative Container
        Sorted   Associative Container
        Multiple Associative Container

Container Types mapped to Standard Containers
=============================================

std::vector:    Sequence    Back        Sequence                    Forward/Reverse/Random Container
std::deque:     Sequence    Front/Back  Sequence                    Forward/Reverse/Random Container
std::list:      Sequence    Front/Back  Sequence                    Forward/Reverse Container
std::set:       Sorted/Simple/Unique    Associative Container       Forward Container
std::map:       Sorted/Pair/Unique      Associative Container       Forward Container
std::multiset:  Sorted/Simple/Multiple  Associative Container       Forward Container
std::multimap:  Sorted/Pair/Multiple    Associative Container       Forward Container


Container Guarantees:

我找到了不错的资源Standard C ++ Containers。也许这就是你们所有人想要的。

向量

建设者

vector<T> v;              Make an empty vector.                                     O(1)
vector<T> v(n);           Make a vector with N elements.                            O(n)
vector<T> v(n, value);    Make a vector with N elements, initialized to value.      O(n)
vector<T> v(begin, end);  Make a vector and copy the elements from begin to end.    O(n)

v.at(i)       Return (or set) the I'th element, with bounds checking.  O(1)
v.size()      Return current number of elements.                       O(1)
v.empty()     Return true if vector is empty.                          O(1)
v.begin()     Return random access iterator to start.                  O(1)
v.end()       Return random access iterator to end.                    O(1)
v.front()     Return the first element.                                O(1)
v.back()      Return the last element.                                 O(1)
v.capacity()  Return maximum number of elements.                       O(1)

修饰符

v.push_back(value)         Add value to end.                                                O(1) (amortized)
v.insert(iterator, value)  Insert value at the position indexed by iterator.                O(n)
v.pop_back()               Remove value from end.                                           O(1)
v.assign(begin, end)       Clear the container and copy in the elements from begin to end.  O(n)
v.erase(iterator)          Erase value indexed by iterator.                                 O(n)
v.erase(begin, end)        Erase the elements from begin to end.                            O(n)

对于其他容器，请参阅页面。

我不知道有哪一个表可以让您一目了然地比较所有表（我不确定这样的表是否可行）。

当然，ISO标准文档详细列出了复杂性要求，有时在各种可读性强的表中，有时在每种特定方法的可读性不高的项目符号中进行枚举。

此外，http： //www.cplusplus.com/reference/stl/上的STL库参考还提供了适当的复杂性要求。

另一个快速查找表可在此github页面上找到

注意：这并不考虑所有容器，例如unordered_map等，但看起来还是不错的。这仅仅是一个更清洁的版本，这
