WebNov 23, 2024 · We know that a permutation must: Have all elements from the input array. Be unique (no repeated permutations). Have no repeated elements in the permutation. This is the end condition of our backtracking algorithm. Once these conditions are satisfied, we can: Add the current permutation to our list of permutations. WebOct 5, 2024 · Use Recursion in Python to Find All Permutations of a String The concept we’ll use in recursion to create permutations is known as backtracking. The idea is that we backtrack for each possible combination that can exist. Let’s take a look at how this recursive method works to help find all combinations of a string in Python:
