In Java

Consider two fractions in the form a/b and c/d, where a, b, c, and d are integers. Given a string describing an arithmetic expression that sums these two fractions in the format a/b + c/d, compute the sum and fully reduce the resulting fraction (i.e., e/f), then save the reduced fraction as a string in the form e/f. For example: The expression 1/2 + 1/6 evaluates to 4/6, which we reduce to the string 2/3. The expression 7/10 + 13/10 evaluates to 20/10, which we reduce to the string 2/1
