WebOct 26, 2024 · To make the permutations of 1234, we have to make the permutations of 234 first and this will be done in the first iteration (i will be 0). For this, permutation (1,3) will be called. 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.
