Write a program to build a class PhanSo that has 2 properties, numerator and denominator. The program has getter and setter methods for properties and has the following functions: - reduce(): minimize fractions - inverse(): inverse fraction - add(PhanSo p2): add 2 fractions - subtract(PhanSo p2): subtract 2 fractions - multiple(PhanSo p2): multiply 2 fractions - divide(PhanSo p2): divide 2 fractions - compare(PhanSo p2): compare 2 fractions. Returns 0 if 2 fractions are equal, 1 if 1st fraction is greater and -1 if 1st fraction is less

class PhanSo:
      def __init__(self, tu, mau):
        """Initializing"""
        self.tu = tu
        self.mau = mau
      
      def setTu(self, tu):
        """Setter for tu"""
        self.tu = tu
      
      def getTu(self):
        """Getter for tu"""
        return self.tu
      
      def setMau(self, mau):
        """Setter for mau"""
        self.mau = mau
      
      def getMau(self):
        """Getter for mau"""
        return self.mau

      def __str__(self):
        """Print"""
        return str(self.tu) + "/" + str(self.mau)

      def __repr__(self):
        """Return a string representation of the fraction for interactive mode."""
        return 'PhanSo({0}, {1})'.format(self.tu, self.mau)
