Topic: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. Analysis: Using the binary method to sort and record the number of

LeetCode-Reverse Bits, 1 Bit and number binary correlation Reverse bits of a given 32 bits unsigned integer. For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as0011100101111000001010010000000 ).The simple method is to traverse it, but this method is very inefficient and seems t

DescribeIn 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 inverse

DescriptionJapan plans to welcome the ACM ICPC World Finals and a lot of roads must is built for the venue. Japan is Tall island with N cities on the East coast and M cities on the West coast (M InputThe input file starts with t-the number of test cases. Each test case is starts with three numbers–n, M, K. Each of the next K lines contains, numbers–the numbers of cities connected by the superhighway. The first one is the

Number of reverse order = Inverse number of two sub-sequences + inverse number of this sequenceWe know that when the sequence is sorted by two-way merging, the sequence is split into several sub-sequences, the sub-sequences are sorted first, and the sub-sequences are combined to form the final ordered sequence. Two-way
