Web26. okt 2024 · Now in this permutation (where elements are 2, 3 and 4), we need to make the permutations of 3 and 4 first. And thus, permutation (2,3) will be called to do so. Similarly, permutation (3,3) will be called at the end. At this point, we have to make the permutations of only one digit with the index 3 and it has only one permutation i.e., itself.
