This is the ninth video of the "DP On Strings" series in this playlist.
In this video we will try to solve a good DP on strings problem : Palindrome Partitioning | Using Blue Print | DP On Strings | Leetcode 131 | DP Concepts & Qns-27 | codestorywithMIK


I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Approaches Summary :
The approach uses a combination of dynamic programming and backtracking to find all possible palindromic partitions of a given string. Here's a summary:

Dynamic Programming (DP) Table Construction:

A 2D boolean array t is used to store whether substrings s[i...j] are palindromes.
Single-character substrings are always palindromes.
For substrings of length 2 or more, the array is populated based on whether the characters at the ends are the same and if the substring between them is also a palindrome.
Backtracking:

The solve method recursively explores all possible partitions of the string using the precomputed DP table.
If a substring is identified as a palindrome, it is added to the current partition, and the method proceeds to partition the remainder of the string.
Once the entire string is partitioned, the result is added to the list of results.
Result Collection:

The final list of palindromic partitions is returned after all possible partitions have been explored.
This approach efficiently finds all palindromic partitions by leveraging the DP table for quick palindrome checks and backtracking to explore all partition possibilities.
