Count of Palindromic Substrings
Problem Statement
Given a string, find the total number of palindromic substrings in it. Please note we need to find the total number of substrings and not subsequences.
Example 1:
Input: "abdbca"
Output: 7
Explanation: Here are the palindromic substrings, "a", "b", "d", "b", "c", "a", "bdb".
Example 2:
Input: = "cddpd"
Output: 7
Explanation: Here are the palindromic substrings, "c", "d", "d", "p", "d", "dd", "dpd".
Example 3:
Input: = "pqr"
Output: 3
Explanation: Here are the palindromic substrings,"p", "q", "r".
Constraints:
1 <= st.length <= 1000stconsists only of lowercase English letters.

🎨 Explain it visually
Build the mental picture, not memorization.
I just read a lesson on **Count of Palindromic Substrings** (DSA) and want to truly understand it. Explain Count of Palindromic Substrings from first principles using ONE vivid real-world analogy and a visual mental model — draw it as ASCII art or a clear step-by-step diagram — with a concrete example using real numbers. Then ask me one question to check I got the mental picture, and wait for my reply. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🤔 Walk me through it (interactive)
Socratic — adapts to where you're stuck.
Teach me **Count of Palindromic Substrings** interactively. Ask me ONE guiding question at a time, wait for my answer, and adapt to my confusion — build the idea with me step by step instead of explaining it all at once. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧪 Quiz me & fix my gaps
Active recall exposes what you missed.
Quiz me on **Count of Palindromic Substrings** with 5 questions, easy to tricky, ONE at a time. Tell me if each answer is right; at the end, explain clearly what I got wrong and why. If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
🧠 Make it stick
Intuition + hook + flashcards for long-term memory.
Help me remember **Count of Palindromic Substrings** for the long term: give the one-sentence intuition, a memorable hook/mnemonic, a tiny worked example, and 3 active-recall flashcards (Q -> A). If you're unsure or a claim isn't standard, say so and reason from first principles instead of guessing.
