Write a command line program in the language of your choice that will take operations on fractions as an input and produce a fractional result.
Legal operators shall be *, /, +, - (multiply, divide, add, subtract).
Operands and operators shall be separated by one or more spaces.
Mixed numbers will be represented by whole_numerator/denominator. e.g. "3_1/4".
Improper fractions and whole numbers are also allowed as operands.
Example run
? 1/2 * 3_3/4
= 1_7/8
? 2_3/8 + 9/8
= 3_1/2
gradle run -q --console=plain
