Question

Find the total number of palindromic substrings in a given string STR.

"abbc"

The palindromic substrings are: ["a", "b", "b", "c", "bb"]. Total 5 palindromic substrings.

Accepted Answer

Count the total number of palindromic substrings in a given string.

Iterate through each character in the string and expand around it to find palindromic substrings.
Use dynamic programming to store previously calculated palindromic substrings.
Consider both odd and even length palindromes while counting.
Example: For input 'abbc', palindromic substrings are ['a', 'b', 'b', 'c', 'bb']. Total count is 5.
