Web7. jan 2024 · But this method doesn’t provide unique permutations. Hence to ensure that any permutation is not repeated, we use a set and follow the below conditions: If the permutation is not present in the set, print it and insert it in the set. Increment the count of number of unique permutations. Else, move on to the next permutation. WebBacktracking can be very inefficient, especially when the number of possible solutions or the size of the input is large. Therefore, it is important to carefully analyze the problem and develop an efficient backtracking algorithm. Example: 0046 - Permutations (Medium)
