WebNov 11, 2024 · As we can see in the picture and explanation in the last section, generating permutations can be formulated in a simple recursive algorithm. At each recursion step, we have the permutation we generated thus far and the set of remaining objects to permute. We’re done once there are no objects left to permute (the remaining object list is empty). WebBasically I use a Set to recursively generate the permutations. To illustrate, the first position can hold all possible values, the second all possible values except the first value, and so on. When we get to the last position, there is only one possibility.

WebAug 19, 2024 · In other words, you simply traverse the tree, and when you reach the leaf you print the permutation. Then you backtrack one level up, and try another option. Moving one level up the tree is what we call the backtracking in this case. As for implementation, the backtracking is usually implemented using recursive call(s) as in your example. WebOct 26, 2024 · So, recursion seems to be the most generic way to solve the problem. So, let's make a permutation function to do this. array = [1, 2, 3, 4] function permutation(start, end): #i will go from start to end for i -> (start, end+1): permutation(start+1,end) Here, we have just implemented the above-stated logic.
