Suppose that a class USCurrency has been defined for storing a currency amount in dollars and cents (both integers) where one dollar equals 100 cents. The class code is linked under the problem title in "Related Links". The class includes the following members:

private int totalCents total number of dollars and cents
public USCurrency(int dollars, int cents) constructs a currency object with given dollars and cents
public int dollars() returns the dollars
public int cents() returns the cents
public String toString() returns a String in $d.cc notation (-$d.cc for negative amounts)
public USCurrency add(USCurrency other) returns the result of adding another currency amount to this one
public USCurrency subtract(USCurrency other) returns result of subtracting other currency amount from this one

Your task is to modify the class to be Comparable by adding an appropriate compareTo method. The currency objects should be compared in the obvious way, with smaller currency amounts considered "less" than larger currency amounts (e.g., -$13.45 < -$2.03 < $5.13 < $98.06).

A currency amount can be negative. The cents method returns values in the range of 0 to 99 for nonnegative amounts and returns values in the range of 0 to -99 for negative currency amounts.
