the reference row;6, two-level index access requires two index lookups, not one at a time;　Viii. SummaryThere are three principles to keep in mind when selecting indexes and writing queries using these indexes:1, single-line access is the slowest. Especially in mechanical hard drives (SSD random I/O is much faster, but this is still true).If the server reads a chunk of data from storage just to get one of the rows,So a lot of work is wasted, and it's best to read a block that contains as many r

This is a simple sort, the reason why put this problem above, because I am in this problem is too much WA, WA 7 times, in the middle to find outA mistake, that is, in the penultimate and the penultimate equal circumstances I did not output their number, corrected or WA, finally I found that the original is each groupOutput a blank line between data .....

pointer to operate, so efficiency is quite efficient. There are many different ways to use fseek to manipulate files, and the efficiency may also vary slightly, and here are two common approaches.Method One:First, find the last EOF of the file by fseek, then find the beginning of the last line, take this row of data, then find the starting position of the next line, then take the position of this line, and so on, until the $num line is found.* * This method has a problem with the test, look at

)(6,0, 1, 2, 1, 0)(6, 0, 1, 2, 0, 0, 1)You will find that at the time of the penultimate assignment, the n-1 person will be opposed (P=3 exception), so the last nth person wants to get more than half of the votes, it is necessary to put hope in the penultimate 1~ (n-2) this n-2 person. So just give them (n-2)/2+1 The number of diamonds a person has to give them more than n-1, and they will support you. So t

before the large number is placed;Then compare the 2nd and 3rd numbers, put the decimal before the large number, so continue until the last two numbers are compared, the decimal place before the large number of places;At the end of the first trip, the largest number was put to the last.On the second trip:The comparison is still started from the first logarithm (because the 1th number is no longer less than the 2nd number because of the 2nd and 3rd number of interchanges), the decimal place is p

Reverse Access listWe still use a list to score from high to low to show 3 students in the class:>>> L = ['Adam'Lisa'Bart ']At this time, the teacher said, please score the lowest students stand out.To write code to accomplish this task, we can count the list first and find that it contains 3 elements, so the index of the last element is 2:>>> print l[2]bartIs there a simpler way?Yes!Bart classmate is the last, commonly known as the countdown first, so we can use the 1 index to r

-------------------------------------------------------------------------------- Add right-click menu in FCKeditorI am going to introduce how to configure FCKeditor on the Internet. There are many examples of how to streamline it. If you need it, You can Google it. I don't need to go into details here. Now we will introduce how to customize this editor, including how to add items on the toolbar, generate responses, and right-click the menu. It seems very easy! The book is back to the beginning.1

situations: 1. n-S has appeared in the previous sequence, then obviously this split is not reliable 2. the N-S is larger than the penultimate number. For this kind, we can adjust the size of the last number and the penultimate number to make this split true, assuming that the last number is, the second to the last is B, as long as the A-1, B + 1 is good. Of course, if the A-1 = B + 1 this split is not reli

(). Those answers, throw you a 16GB file and die. The implementation of the tail command is an honest method: Jump to the end of the file with Os.seek, Os.tell determine the file size Set a suitable buf size, assuming it is 1024. Loop Os.seek back from the end of the file buf size, determine the number of carriage returns in the read content, and the number of return characters Stop the loop when the number of carriage returns is greater than or equal to 2. Determine the position
