Palindromic partitions

Detailed guide and Python implementation for the 'Palindromic partitions' problem.

Problem Statement

Easy

Write a function palindromic_partitions(s) that returns all possible ways to partition the string s such that every substring in the partition is a palindrome. Return a sorted list of partitions, where each partition is a list of strings. Sort by comparing partitions lexicographically.

Constraints
  • 1 <= len(s) <= 16
  • s contains only lowercase English letters

Examples

Example 1
Input
s = 'aab'
Output
[['a', 'a', 'b'], ['aa', 'b']]
Explanation

'a','a','b' are all palindromes. 'aa' is a palindrome and 'b' is a palindrome. 'aab' itself is not a palindrome.

Example 2
Input
s = 'a'
Output
[['a']]
Explanation

A single character is always a palindrome.

Example 3
Input
s = 'aba'
Output
[['a', 'b', 'a'], ['aba']]
Explanation

Both ['a','b','a'] and ['aba'] consist of only palindromic substrings.

Need a Hint?
Consider using Recursion-specific data structures like sets or heaps.
Edge Cases to Watch
  • Empty input structures
  • Single element inputs
  • Large numerical bounds
