Program Code – Tackling Python Programming Interview Questions: A Comprehensive Guide
# Problem: Given an array of distinct integers, return all possible permutations.
def permute(nums):
'''
This function returns all possible permutations of a list of numbers.
:param nums: List of distinct integers
:return: A list of all possible permutations of nums
'''
# Base case: if nums is empty, there is only one permutation - an empty list
if len(nums) == 0:
return [[]]
# Initialize an empty list to store all permutations
permutations = []
# Loop through each number in the input list
for i in range(len(nums)):
# Extract the current number
current_num = nums[i]
# Get the rest of the numbers excluding the current one
remaining_nums = nums[:i] + nums[i+1:]
# Recursively call permute to get permutations of the remaining numbers
for p in permute(remaining_nums):
# Add the current number to the beginning of each permutation of the remaining numbers,
# and add the new permutation to the list of all permutations
permutations.append([current_num] + p)
return permutations
# Example usage
if __name__ == '__main__':
nums = [1, 2, 3]
print(permute(nums))
Heading:
Code Output:
[[1, 2, 3], [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2], [3, 2, 1]]
Code Explanation:
This code snippet tackles the popular Python programming interview question of generating all possible permutations of a given list of distinct integers. The logic behind this solution centers around recursion and the divide-and-conquer strategy.
- Base Case: When the input list
numsis empty, there’s only one permutation possible – an empty list. This acts as our base case to stop the recursion. - Recursive Case: For any list with elements, the approach involves iterating over each element (
current_num) in the list. For every iteration:- The element is temporarily removed from the list, resulting in a
remaining_numslist that excludes thecurrent_num. - A recursive call is made with this new list. This call will return all permutations of
remaining_nums. - Each of these returned permutations is then combined with
current_num(placed at the beginning) to generate a new set of permutations that includecurrent_num. - These new permutations are collected in a list (
permutations) that accumulates all possible permutations of the original list.
- The element is temporarily removed from the list, resulting in a
- Completeness and Return: This process is carried through for every element in the input list, ensuring that we explore every possible position for each number in the permutations. Finally, the list of accumulated permutations is returned.
Through this methodology, the code successfully explores all permutations by systematically exploring and combining smaller permutations, achieving the objective robustly and efficiently.
