Given a string, split it into palindromic substrings using the fewest possible cuts.
You are given a string s. Your task is to divide s into one or more contiguous substrings such that every substring is a palindrome.
Return the minimum number of cuts needed so that every part of the partition is palindromic.
A cut is made between two adjacent characters. If the whole string is already a palindrome, the answer is 0.
Find the smallest number of cuts required to partition the entire string into palindromic pieces.
s.s into palindromic substrings.1 <= s.length <= 2000 is a common interview-scale constraint for this problem.Example 1
Input
s = "aab"
Output
1
Explanation
One optimal partition is "aa" | "b", which uses 1 cut.
Example 2
Input
s = "a"
Output
0
Explanation
A single character is already a palindrome, so no cuts are needed.
Example 3
Input
s = "abccbc"
Output
2
Explanation
One optimal partition is "a" | "bccb" | "c", which uses 2 cuts.
