Solution: Palindromic Substrings
Understand how to count all palindromic substrings within a string using dynamic programming. This lesson guides you through the naive approach, its inefficiencies, and an optimized method leveraging a lookup table. Learn to implement and analyze a solution that reduces time complexity from cubic to quadratic while carefully managing space usage.
Statement
Given a string, s, return the number of palindromic substrings contained in it. A substring is a contiguous sequence of characters in a string. A palindrome is a phrase, word, or sequence that reads the same forward and backward.
Constraints:
s.length...
