docs: add explanation for type conversion solution

[tarun10898]

This PR adds a simple Python script that demonstrates type conversion between integers, floats, and strings. It reads user input, performs conversions, and prints the results in a structured format.

• Added solve() function to:
  • Read an integer, float, and string from user input
  • Convert integer to float and float to integer
  • Convert string to integer (assuming valid numeric input)
  • Print all values and their converted forms

✅ How to Test

1. Run the script.
2. Provide:
   • An integer (e.g., 42)
   • A float (e.g., 3.14)
   • A numeric string (e.g., "100")
3. Verify that the output shows correct conversions:

   Integer: 42
   Integer to float: 42.0
   Float: 3.14
   Float to integer: 3
   String: 100
   String to integer: 100
