Solution: Palindromic Substrings
Explore how to efficiently count palindromic substrings within a string using dynamic programming. This lesson guides you through creating a lookup table to avoid redundant checks, optimizing the solution from a naive O(n³) approach to O(n²) time complexity. Understand how to apply memoization for substrings of varying lengths and gain proficiency in dynamic programming techniques for string problems.
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...
