Expert Solution
Step 1: Elaborating the Algorithm
  1. Create a function permute that takes two parameters: the array to be permuted and the current index.
  2. If the current index is equal to the length of the array then it means we have generated a permutation and Print the array.
  3. Otherwise iterate through the array starting from the current index :
    • a. Swap the current element with the element at the current index.
    • b. Recursively call permute with the incremented current index.
    • c. Swap back the elements to maintain the original array for the next iteration.
