Longest Common Substring
Problem Statement
Given two strings 's1' and 's2', find the length of the longest substring which is common in both the strings.
Example 1:
Input: s1 = "abdca"
s2 = "cbda"
Output: 2
Explanation: The longest common substring is "bd".
Example 2:
Input: s1 = "passport"
s2 = "ppsspt"
Output: 3
Explanation: The longest common substring is "ssp".
Constraints:
- 1 <= s1.length, s2.length <= 1000`
s1ands2consist of only lowercase English characters.

🎨 Explain it visually
Build the mental picture, not memorization.
I just read a lesson on **Longest Common Substring** (DSA) and want to truly understand it. Explain Longest Common Substring 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 **Longest Common Substring** 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.
