Math ranges kata

Basics

An integer range can be defined in the following ways:

• Use brackets [] for inclusive limits
• Use parenthesis () for non inclusive limits
• Use curly braces {} for enum lists

All these examples are equivalent:

• [1, 6]
• (0, 7)
• [1, 7)
• (0, 6]
• {1, 2, 3, 4, 5, 6}

Proposed exercise

Implement the function get_all_points(Range):

• [1, 6] → {1, 2, 3, 4, 5, 6}
• (2, 4) → {3}
• {1, 2, 3} → {1, 2, 3}
