Reverse a Number (while)

The variable n holds 1234. Use a while loop to build its reverse (4321) and print the output shown in Expected Output.

Build the result with rev = rev * 10 + n % 10; while peeling digits off n.

Expected Output:

Reversed: 4321↵

= newline. The output ends with a newline — print one after the last line.
