Activity 2: Investigate (Parsons Problem)

Drag and reorder the blocks to build the correct OCR string-handling program.
The program should ask for a word, then print its .length.
Use .left(2) and .right(2) to show the start and end.
Finish by printing all three outputs in order.

Your Program

Activity 3: Modify

The starter program already asks for a first name and surname.
Add one more print line to show the first initial and the surname.
Keep the existing greeting working.

Run your code to check it.

Activity 4: Make

Use the IDE starter scaffold to build a string-handling program.
Ask for one input string, then use .length, .left, and .right.
Also show .upper and .lower versions of the text.
Add one ASCII example with ASC or CHR.
Add one // comment to explain one string operation.
