2. Whitespace

• Always use 4 spaces for indentation. Never use tabs.
• The max character count per line is 100.
• Operator Prefix Spacing: Never put a space between a prefix operator and its immediate first operand, but do use spaces to separate subsequent operands.
  • +^a 2 ^b 2 is preferred over + ^ a 2 ^ b 2 or +^a 2^b 2.
  • This only applies to arithmetic operators. For binary comparison operators, you should have a space between every token, but it’s not necessary for unary operators.
