Test Status Code Input and Output
1   Fail

Error in solution: Line: 8 Column: 15 Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

2   Fail

Error in solution: Line: 8 Column: 15 Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.
