africa map vector

In STL, the basic containers include string, vector, list, deque, set, and map. Set and map are unordered storage elements. They can only be accessed through the interfaces provided by it. Set: Set, used to determine whether an element is in a group and is rarely used.Map: ing, which is equivalent to a dictionary. It maps a value to another value. If you want

concurrentmodificationexception is thrown when the iterator method is invoked, so the exception must be caught.Stack classStack inherits from the vector, implementing a LIFO stack. Stack provides 5 additional methods that allow vectors to be used as stacks. Basic push and Pop methods, and Peek method to get the top of the stack elements, empty method test stack is empty, the search method detects an element in the stack position. Stack is just create

Question: uva11991easy problem from rujia Liu? (MAP + vector) Give you n numbers, which may be repeated. Then, in m queries, ask the subscript of the k V. If such a number does not exist, output 0. Solution: map each number and subscript for one-to-one ing, but because the same number appears multiple times, an array is required and the length is not certai

in the red and black tree based set and map, but also to the list.In summary, vectors are suitable for trailing inserts, but it is not possible to take into account the performance of lookups, as the vectors of the binary lookup require reordering, or the vector is ordered to remain in order at insertion, so that the trailing insertion is not possible.But Vector

1. Vector (continuous space storage, you can use the [] operator to quickly access random elements, quickly insert elements at the end, but in the middle of the sequence of insertion, delete elements slow, and if the initial allocation of space is not enough, there is a redistribution of larger space, and then copy the performance cost . 2. Deque (continuous of small pieces, the small pieces are connected by a linked list, and in fact there is a poin

New Skill get!ProblemFor containers inside C + +, we can use iterator for easy traversal. But when we make changes through iterator to Vector/map and so on, we need to be careful, because operations often lead to iterator failure, and subsequent behavior becomes unpredictable. Like what:#include The description of std::vector::erase in Cplusplus's reference is:

Value is primarily used to store values and can also be used for conversion of valuesEx:value A = value ("123")Value B = value ("AA")Log ("a=%s,b=%d", a.asstring (). C_STR (), B.asint ());Vectors are primarily used to store specific data spaces for continuous subscript accessVectorA.pushback (Label1);Map is stored by key value (the key value can be any value)MapB.insert (1,a);Vector is a continuous
