Factorial complexity algorithms have a runtime of O(n!). This is the worst case scenario for an algorithm. Factorial complexity algorithms are very inefficient and should be avoided.
def generate_permutations(s):
# Base case: If the string length is 1, return a list containing the string
if len(s) == 1:
return [s]
# Initialize the result list
permutations = []
# Recursively generate all permutations
for i in range(len(s)):
# Current character
current_char = s[i]
# Remaining characters
remaining_chars = s[:i] + s[i + 1 :]
# Generate all permutations of the remaining characters
for perm in generate_permutations(remaining_chars):
# Add the current character to the front of each generated permutation
permutations.append(current_char + perm)
return permutations
