Leetcode Problem 647. Palindromic Substrings

647. Palindromic Substrings

Leetcode Solutions

Initialize a count variable to 0 to keep track of palindromic substrings.
Iterate through the string with a loop, treating each index as the center of a potential palindrome.
For each center, expand outwards for odd and even length palindromes: a. For odd-length palindromes, set left and right pointers to the center index. b. For even-length palindromes, set the left pointer to the center index and the right pointer to the next index.
While the left and right pointers are within the bounds of the string and the characters at these pointers are equal, increment the count and move the pointers outward.
Return the count after processing all centers.
