2. Currency Recognition Implement a function that will determine if a string represents a valid currency amount Such strings will have the following properties: * The amount must consist of base-10 digits * The amount may optionally contain thousands separators using the ',' character. * If thousands separators are present, they must be present at each thousands increment. * The amount must be prefixed by the currency symbol. We support US Dollars ($), Euros (C), and Japanese Yen () only. * Negative amounts may be indicated either by a negative sign before the currency symbol or by enclosing the amount (including currency symbol) in parentheses, such as ($450) * Dollar and Euro amounts may contain an amount of cents, represented to exactly two digits of precision. * If a decimal point is present, the cents must be specified * Yen amounts may not contain decimal points * Amounts may not contain a leading zero, unless it is zero Dollars or Euros and cents are specified * Any other characters, including leading or trailing whitespace, is invalid Some examples: Valid: "$450" * "-23" * "(x2400)" * "$4,500.00" * "0.25" Invalid: * "cat" *"25" * "$45,0" * "(350" *"(-$3.50) * "*120.00" 2.
