+
+### Tool:
+ChatGPT
+
+### Prompt/Command:
+"You are helping to create original programming questions for a coding platform. For each topic and difficulty level, generate a unique question that includes:
+
+Title: A clear, descriptive name
+
+Topic: One of: Arrays, LinkedList, Binary Tree, Graphs, Dynamic Programming, Trees, Greedy, Two Pointers, Sorting, Recursion, Strings
+
+Difficulty: Easy, Medium, or Hard
+
+Description: A clear explanation of the problem in markdown format (no \n escapes, use actual line breaks). Include examples.
+
+Test Cases: In JSON format with "input" and "output" for each case
+
+Guidelines:
+
+Do NOT copy or adapt problems from LeetCode, Kattis, or other known platforms
+
+Ensure the problem is well-scoped and appropriate for the difficulty level
+
+Use clear and simple input/output formats
+
+Avoid using images or external references
+
+Make descriptions readable with proper markdown formatting (headers, lists, code blocks)
+
+Example Output Format:
+
+Title: Count Even Numbers
+Topic: Arrays
+Difficulty: Easy
+Description: Given an array of integers, return the count of even numbers.
+
+Example
+Input: [1, 2, 3, 4]
+Output: 2
+
+Test Cases:
+
+json
+{
+  "cases": [
+    {
+      "input": "[1, 2, 3, 4]",
+      "output": "2"
+    },
+    {
+      "input": "[0, -2, 5]",
+      "output": "2"
+    }
+  ]
+}
+
+Please start with LinkedList for easy, medium and hard, all 3."
+
+Subsequent prompts are just something like: "Proceed with "Trees", "Greedy""
+
+### Output Summary:
+Questions generated with the prompt descriptions. E.g:
+"Sure! Here are three original LinkedList problems (Easy, Medium, and Hard) written in the requested format:..."
