Write a procedure

bool read_rational(int& num, int& den);

that tries to read a rational number given in the form “numerator”/“denominator”, and stores these two values in num and den, respectively. Additionally, you must remove all common factors from num and den. Furthermore, if the input had a rational number, you must return true; otherwise you must returna false. For instance, this code

int num, den; while (read_rational(num, den)) cout << num << ' ' << den << endl;

with this input

66/12
100/100

should print

11 2
1 1

Precondition

1 ≤ num ≤ 109 and 1 ≤ den ≤ 109

Observation You only need to submit the required procedure; your main program will be ignored.
