00:00I have a little lecture for a good developer, and I have asked what quality is a good developer.
00:06We discussed that a good developer has a clean code, a bug-free code.
00:12In this lecture, I will expand the concept of this concept,
00:17because we talked about functions.
00:19I will give you a definition of an ideal function.
00:24Basically, I was learning as an experienced developer.
00:29We had a concept that exists,
00:36and then we define a perfect function.
00:43Then we follow the best code.
00:48However, if you have mechanics,
00:53you will know that a machine exists not,
00:55which has a efficiency of 100 percent.
00:57You will know that a machine exists not,
00:59or that a perpetual motion machine says,
01:01that it exists not,
01:03which has zero energy and works.
01:05Here, zero watts can be zero energy.
01:07So, you have to follow this definition,
01:11that we have an idealistic function.
01:13So, first of all,
01:15we will see what idealistic function is.
01:17Imagine that you have a function.
01:20Let's say,
01:21let's say,
01:22I will add a box.
01:23Okay?
01:24And this box is some code.
01:26Okay?
01:27However,
01:28this box is some input.
01:30And again,
01:32this is some output.
01:33This is a output.
01:34In,
01:35and out.
01:37Now,
01:38this is a function.
01:39Now,
01:40this is a function.
01:41If I say,
01:43let's say,
01:44an idealistic function is.
01:46So,
01:47this is an idealistic function.
01:48There are two properties.
01:50The first property is
01:53that this is
01:54always the same output
01:56to the same output.
01:57Irrespective of the run.
01:59If you have one million times
02:02to the same output
02:04to the same output
02:05to the same output.
02:06that is the same result.
02:07So,
02:08this is the same result.
02:09This is the same result.
02:10This is the same result.
02:11So,
02:12if you have one,
02:13you should say,
02:14one,
02:15one,
02:16I will enter.
02:17And,
02:18if you have one,
02:19the function,
02:20one,
02:21one,
02:22one,
02:23one,
02:24two,
02:25or two,
02:26one,
02:27one,
02:28two,
02:29one.
02:30If you have one million times,
02:31one,
02:32one,
02:33one,
02:34two,
02:35one add
