#graph-theory#number-theory#shortest-path#sorting#bitmasks Let A[0...n - 1] be an array of n distinct positive integers. If i < j and A[i] > A[j] then the pair (i, j) is called an inversion of A. Given n and an array A your task is to find the number of inversions of...
2. Take A[1] and find its position in sorted array B via a binary search. The number of inversions for this element will be one less than the index number of its position in B since every lower number that appears after the first element of A will be an inversion. 2a. accumulate th...
Given an array of pairs p[]p[] of length n(≤100000)n(≤100000) I want to do the following: Task 1: Given q(≤100000)q(≤100000) queries and L,R,(pair p)L,R,(pair p), output the number of pairs < p in the range [L,R][L,R]. Task 2: Count the number of inversions...
The array contains N elements . All elements are in the range from 1 to 1,000,000,000. Input The first line contains one integer , indicating the size of the array. The second line contains elements in the array. · 50% test cases guarantee that ...
This paper presents an inversion/non-inversion implementation for a fabricated 11,424 gate-count dynamic optically reconfigurable gate array VLSI. Based on that implementation, three factors are discussed: gate density, reconfiguration frequency per unit of laser power, and optical power consumption....

The output of the iterator is an array of fixed lengthn. Methods In addition to thecommon iterator methods, this iterator object has the following methods. Theselfparameter is the iterator object. • Number(self): return the number of iterations required to step through the iterator, assuming...
