@KlausD. It wouldn't really be "magic" for super() to use the right base class; if it simply referred to the superclass, as its name suggests it would, then there would be no error, and this is the behaviour in single-inheritance languages like Java; Java programmers don't consider it magic that super refers to the superclass. — kaya3 26 secs ago

Questions that ask "where do I start?" or for pointers are typically too broad and are not a good fit for this site. Give a good read over Where to Start. The best thing is to do some research on the topic yourself, find two or three, analyze them, determine if they work for you or not, and try them out. And edit your post when you have a specific question about something you have attempted to do. — AChampion 56 secs ago

Have gone through this, but why it doesn't suggest murmur3 which is one of the fastest and is rare collision algorithm according to this study softwareengineering.stackexchange.com/a/145633. Even ES uses mumur3 to generate doc id — lucifer 43 secs ago

If you debug this, inspecting the variables during execution, you will see what is wrong. The biggest missing skill in beginner programmers is debugging. My advice, learn to debug and get ahead. It will make a massive difference to your future programming outcomes. — David Heffernan 55 secs ago

@Bergi, I need solving that as in this tutorial for C++ programmers [link] (geeksforgeeks.org/find-closest-element-binary-search-tree) — Max_ReFactor 23 secs ago

@TanveerBadar: You're welcome. I'm joshing Mads here because for the last several decades now there has been a tension between making the spec more precise but at the same time keeping it readable by line-of-business programmers who have not studied theoretical mathematics. Type checking, definite assignment checking, nullability checking, all that could be described more "mathematically" in the specification but Anders and Mads have quite reasonably opted to limit the amount of theory in the spec. — Eric Lippert 25 secs ago

Welcome to Stack Overflow. SO is a question and answer site for professional and enthusiast programmers. The goal is that you add some code of your own to your question to show at least the research effort you made to solve this yourself. — Cyrus 36 secs ago

@KenWhite no offence, but the fact this question is not strictly related with programming code, it doesn't mean it is not relevant to programmers that create Apple app bundles and are trying to sign them. Right now I'm in the process of building a bash script that does this several steps in a single call. — Nuno Santos 57 secs ago

StackOverflow is not programmers -to-hire website - we solve problems, not create whole solutions for you. — Zydnar 29 secs ago

@AndrewHenle: Code which relies upon "documented behaviors characteristic of the environment" should only be expected to work as desired when run in environments with the appropriate characteristic behaviors. On the other hand, most code will only ever be called upon to run in execution environments with some specific known characteristics. One of the reasons for C's popularity and usefulness is the fact that simple implementations can allow programmers to exploit characteristics of the target environment that programmers know about, without the implementations having to understand them. — supercat 10 secs ago

some of my seniors told u need to start solving competitive programming to bag a good job -- I'll be honest that in my experience, most of these competitive programmers couldn't write a coherent, well-maintained program to save their lives, until a "non-competitive" programmer who has properly learned the language has to tutor them. For example, almost all of these "competitive programming" examples shows arrays declared with an enormous amount of entries. Very few professionally written C++ programs declare arrays like that. — PaulMcKenzie 29 secs ago

The folks who designed IEEE 754 did not decide to have operations return a NaN. They decided to give programmers choices. Floating-point exceptions can be trapped or can produce default results. This is intended to be a programmer choice, but incomplete implementations of IEEE 754 may fail to provide that choice. They are responsible for the decision to produce a NaN rather than to trap, not the IEEE-754 committee. — Eric Postpischil 8 secs ago
