Although, i like your solution.
But i have a question. Is it good practice to right this type of code?
I mean this is not so readable and understandable as compare to basic if else, but it will be efficient i guess.
My main question is where we use these type of logics where we can use if else? What is the benefit? How they help in industry ?

Oh! Thanks for quick reply. Working now :)
