Permutations complexity
Web1 day ago · It should return one because there is only one such pair 4 and 5 It is easy to solve this problem in O (n^2) complexity. But I am looking for a faster solution. I tried to find some dependency according to how many changes it takes to sort a given list, but with poor results algorithm sorting merge mergesort counting Share Follow edited 2 mins ago Heap's algorithm generates all possible permutations of n objects. It was first proposed by B. R. Heap in 1963. The algorithm minimizes movement: it generates each permutation from the previous one by interchanging a single pair of elements; the other n−2 elements are not disturbed. In a 1977 review of … See more In this proof, we'll use the implementation below as Heap's Algorithm. While it is not optimal (see section below) , the implementation is nevertheless still correct and will produce all permutations. The reason for using … See more • Steinhaus–Johnson–Trotter algorithm See more
