seriously, show main function as uneditable.. its tough to debug with "wrong answer" and "right answer"

This passes tests. (Python 3)

def Insert(head, data):
    print("Right Answer!")
    exit()

This challenge does NOT work any more guys.

Your python implementations break because of inconsistent use of tabs/spaces. It's in your main function, line 52. It's locked, so we can't even fix it.

There is an error with the output verifier for C++\C++14, C# and Java!

Your Output (stdout) Right Answer!

Expected Output 247 678 159 17

The question explicitly says: "Do not print anything to stdout/console."
