And whether it's a boy or a girl if they want to implement on the left side, you have to look at the number of people that are already lined up, because you can only exchange adjacent positions. Lg,lb for girls and boys on the left row position, initially 0. Code:

For example GGBBG, if the girl on the left, 0 places do not have to exchange, res=0 satisfied, lg
Search in rotated Sorted ArrayDifficulty: Hard
Suppose a sorted array is rotated on some pivot unknown to you beforehand.
(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2).
You is given a target value to search. If found in the array is return its index, otherwise return-1.
Assume no duplicate exists in the array.
(The next topic will study the existence of duplicate cases search in rotated Sorted Array II)
Problem Solving Ideas:For array search problems, there are approximately three kinds of ti

In general, there are two kinds of design ideas for the sorting algorithm, one based on the comparison and the other not based on the comparison. The book "Introduction to Algorithms" shows the proof: "The optimal time complexity of the algorithm based on the comparison is O (n lg N)". For the algorithm based on comparison, there are three kinds of design ideas, namely: Insert sort, exchange sort and s
During the construction of the station, the structure of the site is very important, whether a new webmaster or experienced webmaster, I believe that this view will not veto, then we should arrange the structure of the site, the following with a new station I have recently done a simple example to analyze.

Last week, LG Display released a document about the 8K display, which refers to a screen with a resolution of 7680 X 4320. LG believes the new standard will become the future of display technology. LG has demonstrated the 8K display at the CES show in Las Vegas. LG says the 8K display has 16 times times the number of p
The recent use of 2.5 of IPhone4 also accidentally broke. Cause is a night iPhone4 in the air across an imperfect arc, floated landed, picked up to see when the screen has fallen off the border, the screen left 1/4 can not be used, but in addition to vibration failure border wear serious, the rest can also be used (broken three iphone, two are screen break, Is the fall of the process is miserable, after the end of the fall can be accepted). Later think, IPhone4 is a freshman bought, and iOS6 acc

It is recommended to write a July BULL: http://blog.csdn.net/v_july_v/article/details/7093204The premise of binary search is that the order of the array has been sorted. Baidu once had an interview: This idea is used to find the smallest absolute value in an array.

The general meaning is as follows: first block the array and then extract the maximum value. Similar to data, data is cleaned and decompos

Use resources in DLL
The most common problem about DLL is how to use the dialog box in DLL. This is a common question about how to use resources in dl l. Here we analyze and solve this problem from the Win32 DLL and mfc d ll aspects.
1. Wi n32 DLL
It is very easy to use the dialog box in Win32 DLL. You only need to add the dialog box resources in your DLL, And you can set the required control on the dialog box. Then, use the DialogBox or CreateDialog functions (or other functions with the same
Sorting, and count sorting.
In general, there are two design ideas for sorting algorithms: Comparison and comparison. The book introduction to algorithms provides a proof that "the optimal time complexity of a comparison-based algorithm is O (n LG n )". There are three designs for comparison-based algorithms: insert sorting, exchange sorting, and select sorting. The time complexity of non-comparison-based sorting algorithms is O (
