What is the goal of the Palindrome Partitioning problem?
To split a string into the fewest possible parts so that each part is a palindrome.

What does the 'minimum cuts' mean in Palindrome Partitioning?
It means the smallest number of cuts needed to divide the string into palindrome parts.

How does dynamic programming help in Palindrome Partitioning?
It stores results of smaller parts (substrings) to avoid repeated work and find minimum cuts efficiently.

What is the role of the 'isPalindrome' table in the DP solution?
It quickly tells if a substring is a palindrome, so we don't check repeatedly during partitioning.

In the DP approach, what does the array 'cuts' represent?
cuts[i] stores the minimum cuts needed for the substring from start to index i.

What is the minimum cuts needed for a string that is already a palindrome?
✗ Incorrect
If the whole string is a palindrome, no cuts are needed.
Which data structure helps to avoid repeated palindrome checks in DP?
✗ Incorrect
A 2D boolean table stores palindrome status for substrings.
What does cuts[i] represent in the DP solution?
✗ Incorrect
cuts[i] stores minimum cuts needed for substring from start to i.
If substring s[j..i] is palindrome, how is cuts[i] updated?
✗ Incorrect
We add one cut after position j-1 to separate palindrome s[j..i].
What is the time complexity of the DP solution for Palindrome Partitioning minimum cuts?
✗ Incorrect
The DP solution runs in O(n^2) time using palindrome table and cuts array.
Explain how dynamic programming is used to find minimum cuts for palindrome partitioning.
Think about storing results for substrings and building up the answer.

Describe the role of the 'isPalindrome' 2D table and the 'cuts' array in the solution.
One helps check palindromes fast, the other tracks minimum cuts.
