Given the expression “a b c d%f-g”, output “aBCDFG”. Explain how you would implement that transformation.

Keep only ASCII alphabetic characters, preserve the first retained character exactly, and convert every later retained character to uppercase. Return an empty string when the input contains no letters.

Function signature: def transform_expression(expression): The input is a string, and the output is the transformed string.

Constraints

0 <= len(expression) <= 1000
The input contains printable ASCII characters.
Only ASCII alphabetic characters are retained.
If letters are present, the first retained letter keeps its original case.

Function Signature
