Write a function which doubles the input. The name of the function should be Twice. It should work for both numbers and words. If the input argument (x) is a number then the output argument (y) is a numerical value, but if the input is a word then the output is a word too (see the examples below). Rules: Usage of basic mathematical operators (+, -, *, /) is not allowed. Examples: x = 5 , y = 10 x = "Exam" , y = "Exam Exam" x = "A" , y = "AA"
