proactiv order number

In daily work, sometimes some activities may need to win the prize or select some spot check lists ,?The order by newid () method is often used for random number selection ,?However, it is possible that distinct should be used together. At this time, such as distinct and order by newid ()?When used at the same time, an error message is displayed. If select distin

Test Instructions:Bobo has a sequence a1,a 2,..., a n. He is allowed to swap, adjacent numbers for no more than k times. Find the minimum number of inversions after his swaps. Note:the number of inversions is the number of pair (I,J) where 1≤i i>a J. InputThe input consists of several tests. For each tests:The first line contains 2 integers n,k (1≤n≤10 5,0≤k≤

Merge sort-Calculate reverse order numberMerge sort uses the thought of divide and conquer, Time complexity O (N*LOGN) dynamic memory utilization can reduce the space overhead;Merge sort can also be used to calculate reverse order number;Number of reverse order: a pair of nu

First, the order number has 3 properties: 1. Uniqueness 2. Not speculative 3. EfficiencyUniqueness and unpredictability needless to say, efficiency is not a frequent database query to avoid duplication.Moreover, the order number is short enough to meet these conditions.I customized the

=1394Title: To a group of numbers, each time you can get the beginning of the number to the end, ask such a sequence of the number of reverse order of the smallest inverse valueTitle Analysis: First Use the tree-like array to reverse the number, the reverse value after each Exchange can be directly calculated, because

I-th number should is equal to the number of receiver which the i-th laser should be directe D at. Both lasers and receivers is numbered from 1 to n. It's guaranteed that

Topic:Enter an array of integers to implement a function to adjust the order of the arrays in the array, so that all the odd digits are in the first half of the array, and the even digits are in the second half of the array.Thinking: The array maintains two pointers, the first pointer initializes the array header, the second pointer initializes to the end of the array, the first pointer points to an even number
