Subsequence Pattern Matching
Problem Statement
Given a string and a pattern, write a method to count the number of times the pattern appears in the string as a subsequence.
Example 1:
Input: string: "baxmx", pattern: "ax"
Output: 2
Explanation: {baxmx, baxmx}.
Example 2:
Input: string: "tomorrow", pattern: "tor"
Output: 4
Explanation: Following are the four occurences: {tomorrow, tomorrow, tomorrow, tomorrow}.

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