Below is the implementation of the above approach: edit The currently found number can not occur again so it is removed from the original n numbers and now the problem reduces to finding the ( k % (n-1)! Suppose the set is like [1,2,3,...,n], contains a total of n! Sergey Kharagorgiev. Read More . By listing and labeling all of the permutations in order, We get the following sequence (ie, for n = 3): "123" "132" "213" "231" "312" "321" Given n and k, return the k th permutation sequence. So each of those with permutations of 3 numbers means there are 6 possible permutations. "312" 6. If n =3 we will get the following sequence: 1. Given n and k, return the kth permutation sequence. The set [1,2,3,…,n] contains a total of n! Dismiss Join GitHub today. The set [1,2,3,…,n] contains a total of n! So, the 1st permutation sequence is “12”.
