After n-th iteration, we should break from the loop and then print the string which is our nth permutation. "231" 5. Permutation and combination are the ways to represent a group of objects by selecting them in a set and forming subsets. When we select the data or objects from a certain group, it is said to be permutations, whereas the order in which they are represented is called combination. Approach 1.
