// EXERCISE: Math Tables
|
|
//
|
|
// Create division, addition and subtraction tables
|
|
//
|
|
// 1. Get the math operation and
|
|
// the size of the table from the user
|
|
//
|
|
// 2. Print the table accordingly
|
|
//
|
|
// 3. Correctly handle the division by zero error
|
|
//
|
|
//
|
|
// BONUS #1
|
|
//
|
|
// Use strings.IndexAny function to detect
|
|
// the valid operations.
|
|
//
|
|
// Search on Google for: golang pkg strings IndexAny
|
|
//
|
|
// BONUS #2

// to escape the characters like this.
|
|
//
|
|
// This happens because those characters have special meaning.
