needs to be installed first.Practice:There are two ways to do this, but you need to build the diagram first. Use the Get function to turn the string into a number. The ID represents the software before the colon, and Fu represents the software behind the colon. To save the ID in Vector son[fu], just like a tree. Then put the ID into the degree + +;The first approach, the topological sort. The Q1 queue with an entry level of 0 and does not need to be

down. If your query overwrites the index, or if the table is MyISAM and needs a range scan (because MyISAM uses prefix compression), the slow situation can occur. Consider the UserInfo table. As mentioned in the previous tutorial. This table has 1,000,000 lines and each state_id has 20,000 records. There is an index on the state_id. This is useful for the following queries. The Q1 statement is as follows: Mysql> SELECT Count (*) from userinfo WHERE s

. It took me one day to get stuck. At night, the ox told me that it was wrong to give me a second. For example, n = 5 m = k = 3 1 2 3 4 10000 In binary mode, the length is 2. The result is incorrect. The correct answer should be 4. Only scan through the monotonous queue. Maintain a maximum value and a minimum value. Ensure that the upper limit conditions are met when the maximum value-Minimum value is used. Then, if the lower bound condition is met, the answer is updated.

Address: Black Box Question: There is a black box for two operations, one is add to save the number in the box, the other is get to find the number in the box, the default box is always arranged from small to large, and then a (1), a (2 ).... A (M) is the number of boxes to be saved, u (1), u (2 ),.... the number of U (n) is not the number of the given number, but here the number of U (n) is inserted into the box a (m, here there is a P (1 Solution: First, sort timeout is used for each loop.

(Too lazy to typeset... ^ w ^)Today, I refreshed my DP question for a day and made it disgusting. I just got a question that can optimize both the slope and the Quadrilateral inequality: HDU 3480 division.Slope optimization... Okay, I forgot how to write ........YY ....................Bingo ....When the slope of a monotonic queue is optimized, monotonous queues are used to maintain the monotonicity of the "excellent" solution, that is, the better the former...Briefly summarize (using F [I] = min

Search for the largest public substring Find the largest common substring in the two strings, for example, "abccade" and "dgcadde". The largest substring is "cad" // Use for to control the loop, which is easier to understand than the following while. Int getcommon (char * S1, char * S2, char ** R1, char ** R2) { Int len1 = strlen (S1 ); Int len2 = strlen (S2 ); Int maxlen = 0; For (INT I = 0; I { For (Int J = 0; j { If (S1 [I] = S2 [J]) // finds the First Equal { Int as = I, B

code. T Indicates the number of errors that can be corrected. For example, (28, 24) the RS code represents a total of 28 characters in length of the block. The length of the Information Code is 24, and the verification code has four inspection symbols. In this Code block consisting of 28 symbols, two scattered or two consecutive symbol errors can be corrected in the code block, however, three or more symbol errors cannot be corrected. For an Information Code Symbol
