How do I generate all permutations of a list?

The problem is that each quotient does not care for previous values, so you need to adjust them.

In this section, we will create a Java program and find the permutation and cyclic permutation of a number. Why are they asking this? Look more closely at what they asked.Given an unsorted permutation array of size N and an integer K ( 1 ≤ K ≤ N ), the task is to sort this permutation array in increasing order in the minimum number of steps, where in each step K elements have to be removed from the array and inserted at the front in increasing order and remaining elements should be in arbitrary order. The number of inversions in the permutation. The input array has n characters, 5 <= n <= 7, and I would like to generate a second array A( C( n , 5 ) , 5 ) that contains all the C( n , 5 ) combinations.Is there a straightforward way to generate all possible permutations of a vector of integers (1 to max 999) that specifically excludes duplicated elements? For example, for a vector with three elements in a range of 1 to 9 the sequence 1 2 3 would be acceptable, as would 1 2 9 but 1 2 2 would be invalid.
