Question about the task Multiplication table
Java Syntax, Level 5, Lesson 4
Resolved
Why is this solution for the multiplication table not accepted?Hello everyone :) Do you see, why my solution is not accepted? I created a multiplication table with the help of a nested for loop and filled the 2D array with it. The output is a 10 × 10 multiplication table, separated by a space. Thank you for your time.
