What is a recursive permutation?

Can you explain what a recursive permutation is?

Sure! A recursive permutation is a method of generating all possible arrangements of a set of elements using recursion.

How does the recursion work in generating permutations?

In recursion, you fix one element and recursively generate permutations of the remaining elements until all arrangements are found.

Can you give me an example of how to implement this in Python?

Absolutely! Here's a simple Python function that uses recursion to generate permutations:

def permute(nums):
    if len(nums) == 0:
        return []
    if len(nums) == 1:
        return [nums]
    result = []
    for i, num in enumerate(nums):
        for p in permute(nums[:i] + nums[i+1:]):
            result.append([num] + p)
    return result
