Balance between vector, map, and list
From: [http://www.codingnow.com/2004/board/view.php? Paster= 776]
I want to create a data structure to store data in an orderly manner for convenient search, and the efficiency of data insertion is not too low.
When the data is almost unchanged, vector is the best solution. We only need to put the data in. After sort
[i], index)); Strvec.push_back (index); Index + =1; }Else{Strvec.push_back (strm[str[i]); } }returnStrvec;}Here, a map is used to hold the key-value pairs for each character and index, and the index is represented by index, starting at 0.The final sequence of numbers is saved with vectors.Loops through the entire string, looking for a character in the map each time, if not found, adds it and t
box:For the choice of coordinate system, depends on your data, if it is a GPS device measurement points, you can directly select 4326, so that the map coordinates can be used directly. If you get coordinates from a network map such as a gold map, you select the appropriate projected coordinate system, or the feature location you create is incorrect.2. Field defi
Maps are associative, andvectors,lists,anddeque are sequential in type. Map: Underlying mechanism rb-tree(red-black tree), automatic ordering of elements, key-value pairs. Vector: operates in a similar way to array, with dynamic space growth. is a continuous space that supports random access. Advantages:? Memory is dynamically growing and does not require a specified memory size.? Support for random access
When vector loops are removed, erase (IT) returns the address of the next iterator, and the insurance practice is to assign it to the IT it= erase (IT)
This is caused by the vector's internal mechanism, so pay special attention to whether the iterator will fail when the vector is erase!
Map can be directly erase (it++);

nbut 1646Internet of Lights and switchesTime Limit: 5000MS Memory Limit:65535KB 64bit IO Format: You is a fan of "Internet of Things" (IoT, IoT), so you build a nice Internet of Lights and switches in your huge mansion. Formally, there is n lights and m switches, each switch controls one or more lights, i.e. pressing that switch flips the Status of those lights (On->off, Off->on).Initially, all the lights is on. Your task is to count the number of ways to turn off, the lights by pressing some c
Title Link: http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemId=4917Test instructions: Every word has some tips words. Enter n words and their tips first. Then the M group queries, each query some words, the dictionary order output these words public tips. (each word contains only lowercase uppercase letters)Idea: For the first word, use the vector array G,g[i] to save all tips for this word. For all words, create a dictionary tree, and at the

Take a look at the Remove2, comment out the Remove1, and delete the Remove2 annotation.Run error, vs2005 Expression:list iterator not incrementable, description list iterator ++iter problem.List is a two-way list, after erase (ITER), ITER expires, printf ("0x%x", ITER); The result is 0, and only the erase return value can point to the next element.
the correct usage of REMOVE1 is: vec.erase (Remove (Vec.begin (), Vec.end (), 5), Vec.end ());the correct usage of Remove2 is:lst.remove
