Palindromic Substrings Problem Statement

You are given a string 'STR'. Your task is to determine the total number of palindromic substrings present in 'STR'.

Example:

Input:

"abbc"

Output:

5

Explanation:

The palindromic substrings in "abbc" are: ["a", "b", "b", "c", "bb"]. Therefore, the total is 5.

Constraints:

1

Question

Palindromic Substrings Problem Statement

You are given a string 'STR'. Your task is to determine the total number of palindromic substrings present in 'STR'.

Example:

Input:

"abbc"

Output:

Explanation:

The palindromic substrings in "abbc" are: ["a", "b", "b", "c", "bb"]. Therefore, the total is 5.

Constraints:

1 <= t <= 100
0 <= N <= 1000
Where 't' is the number of test cases, 'N' is the length of 'STR'.
Time Limit: 1 sec.

Note:

A palindrome reads the same forwards and backwards, such as "abba".

A substring is a contiguous sequence of characters within a string, such as "a", "b", "c", "ab", "bc", "abc" of "abc".

Input format:

The first line contains an integer 't' specifying the number of test cases or queries to be run. Each test case consists of a single string 'STR' for which you must count the palindromic substrings.

Output Format:

For each test case, return the total number of palindromic substrings. Output each result on a new line.

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 the results of subproblems to avoid redundant calculations.
Consider both odd-length and even-length palindromes while counting.
Example: For input 'abbc', the palindromic substrings are ['a', 'b', 'b', 'c', 'bb'], totaling 5.
