microsoft order number

51NodIn one arrangement, if the front and back positions of a pair of numbers are opposite to the size order, that is, the previous number is greater than the subsequent number, then they are called an inverse.The total number of reverse order in a permutation is called the

Ideas:In the process of merging and sorting, one step is to remove the small element from the left and right two arrays in the tmp[] array.The array on the right is actually the element on the right side of the original array. When you take the element to the right without taking the element to the left, the remaining elements on the left side are larger than the first element on the right, i.e. they can form an inverse pair. Assuming that there are now n elements left on the right, the inverse

Problem: in actual business processing, some ticket numbers need to grow automatically, but they cannot be replaced by auto-increment columns.Eg: p031106001 -- the first p represents the purchase order, 031106 represents the date, and the last three are the sequential number. /* 1: Create a table structure for testing */Create Table tablename (Pono char (10), B INT)Go/* 2: Create a view to get the current

Title: Enter an array of integers to implement a function to adjust the order of the numbers in the array so that all the odd digits are in the first half of the array, and all the even digits are given to the second half of the array.This topic requires that the odd number be placed in the first half of the array, even in the second half of the array, so all the odd numbers should be in front of even numbe

} -}The stacking order of stacks with more than 14 elements is calculated, and the time begins to be very long, with each increase of 1, the time increases exponentially.In fact, all of the stack order may be catalain number, Catalain number almost does not need time, very fast, but the Cattleya

Order Number problem solving? $ OrderYmdHis). mt_rand (); is this correct? Why is the gb_0000505 obtained in this way? How likely will this order number be to be the same? ------ Solution -------------------- random number, of course, the probability is the same, but there i

poj2299 Ultra-quicksort tree-like array for inverse number Ultra-quicksort Time Limit: 7000MS Memory Limit: 65536K Total Submissions: 49587 Accepted: 18153 DescriptionIn this problem, you has to analyze a particular sorting algorithm. The algorithm processes a sequence of n distinct integers by swapping, adjacent sequence elements until the sequence is Sorted in ascending

Topic Links:http://acm.hdu.edu.cn/showproblem.php?pid=2689Main topic:The number of exchanges required to convert a sequence of n different elements into an ascending sequence by exchanging two adjacent elementsis how much.For example: 1 2 3 5 4, only need to Exchange 5 and 4, the number of exchanges is 1 times.Ideas:The typical problem of reverse order

The idea is that, to generate the order number, the theory is to generate the order code when the order is saved. So trace the code to the Mage_sales_model_order Save () method. And then tracked down to mage_sales_model_resource_order_abstract this, in view of the characteristics of Magento, or mainly to see _beforesav

Remember: Before the interview was the interviewer asked the resume item in the order number I was what the rules generated, I blew my head, nonsense a pass, rely on! Today in the company's project order number generation, curiosity, looked under, is the online this just.1*2*uniqid-This is what the authorities say:3* G

DescriptionOne measure of ' unsortedness ' in a sequence is the number of the pairs of entries, which is out of order with respect to each Other. For instance, with the letter sequence "Daabec", this measure is 5, since D was greater than four letters E is greater than one letter to it right. This measure was called the number of inversions in the sequence. The s
