This intro problem practices TEXTJOIN. TEXTJOIN combines multiple text values with a delimiter between each value. Update the output cells so each row joins the available pieces with "-" between them. When a piece is missing, skip it without creating repeated "-" characters.
See Examples
Your solution should use cell references so it updates automatically if the input cells change values.
