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
