Tag: merge sort to find the logarithm of inverse numbertitle Link: http://codeforces.com/gym/100609/attachmentsThe main topic: There are n cards, each card has red and blue on both sides, the two sides have written some numbers, the same color of

Problem definition:Suppose A[1...N] is an array with n different numbers. If Ia[j] is called (A[i], a[j]) is an inverse pair for the array A.For example arrays have (2, 1), (3, 1), (8, 6), (8, 1), and (6,1) 5 reverse pairs.To solve this problem

Knowledge overviewWell, I admit that this is my third day winter vacation on the knowledge, but I am now a tall (winter vacation, but I have been selected in the province ...) ）Well, this is an algorithm for finding discrete-mode logarithmThe

Ultra-quicksort In 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 order. For the input

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

The Fibonacci sequence , also known as the Golden Section , refers to a sequence of numbers 0, 1, 1, 2, 3, 5, 8, 13, and 、...... In mathematics, the Fibonacci sequence is defined as follows : F (0) =0,f (1) =1,f (n) =f (n-1) +f (n-2) (n≥2,n∈n*) in

Fast New Year, the company is basically gone, only the best talent in the Republic, the most important posts in each department will stick to their own swivel chair, after all, each person's ability is limited, rather than let them continue to work,
