- Use docker so it works on any machine

How the heck is that possible

Now I know too

Those much extension functions in Kotlin...
Just tries a lot combinations and got reminded of the "Let it go"-Song

There was a computer programming teacher in my 1st semester who taught C. He used to have this conventional way of teaching C like other Engineering subjects which was going to more theories before writing actual codes.
These are the conversations with him.
(First day, a guy asks him some questions.)
Guy: Sir, why do we need to learn C? There are other languages used extensively for other tasks like python,etc. Why bother with this boring C?
Teacher: C is used to learn other languages. After learning C, you can easily learn other languages.
Guy: Sir, where is C's application? Where is it used?
Teacher: It is used in academics to lay foundation for students to learn other languages which are used to build softwares.
(Fucking Hilarious)

(A month after he was asking some questions to students.)
Teacher: What is an array? What is an array-name?
Student 1: Array, is this collection of data that can be stored in a single type.
Teacher: Then what is an array-name?
Student 1: I don't know.
Teacher: (angrily) Array-name is a definition itself.
(We were supposed to answer that. It was a standard definition.)
