Exception Chaining

Write a method loadConfig(String input) that tries to parse input as an integer using Integer.parseInt(). If a NumberFormatException occurs, catch it and throw a new RuntimeException with the message "Config error" and the original exception as the cause.

In main, call loadConfig and catch RuntimeException. Print e.getMessage(), then print "Caused by: " + e.getCause().getClass().getSimpleName().

⚠️ AUTO-INPUT MODE: The input stream will automatically contain 'bad\n'.

Expected Output:

Config error↵
Caused by: NumberFormatException↵

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