/* 🔴CHALLENGE🔴 parse rational numbers!🔰 Write a program in any language which takes an input of the following form and parses the two rational numbers from it and performs the addition operator and returns the result as a fraction (rational number) again. Exalmple: input 5/6+3/4 output: 19/12 You should simplify the result of the addtion before printing it. For example if you get 8/12 you should print 2/3.
