In case anyone doesn´t understand, the important value means how it´s code is prioritized (in some cases properties collide). ! important means not important, so nothing will happen. (Apparently people don't get a joke)
artin majidi tf? at least know what you’re talking about before you try to educate someone on something lmao !important is a css property which gives the attribute it’s used upon the highest precedence so basically the joke is if you use !important you’ll always have the highest priority given the context of the joke (he was literally using css) we can safely assume he was talking about the !important attribute in css, instead of using ! as “not”
@@artinmajidi1654 !important means a lot , !importat means important, u should study css to understand it, simply it makes the code stronger so the system will do it (because it is important), i advise u not to depend on it all the time or your project will fail.

Can you give a real world example where inverting a binary tree is required. What would the application be, and why would it be necessary to invert a binary tree. Binary trees resemble what we used 30+ years ago for rudimentary AI, to try to understand written text, or a complex SQL select statement, but what practical use cases are there for most programmers in business today?
Wondering if the standing out with !important was a joke? Discussion about that seems a little confusing down here and I am not exerienced enough to be sure if good practice or not :D I get usage of !important as a bad practice generally, it says - I do not want to have all states defined in deterministic way, only these are mandatory and override any state overlap by important values. And that generally can get out of hand very quickly. By quick search did not found any good reason for usage elsewhere than styles, so I guess that it was a joke most probably.
To avoid r/whooshing anybody, ill explain it here. Im javascript ! means "not". Therefore javascript was making a joke that css is not important. But in css, if you want to override all variables with a value, you have to use the exclamation mark (!). Therefore, css thinks javascript said that she is important. r/whoosh
