Stack Data Structure Tutorial - Solve Coding Challenges

[@SuperHARIS14]

at 1:53:25 its possible that the expression is "5 - ( -2)". Note the space before the "-" so the result won't be correct. We can solve it by looking at the last element in the stack instead. if(s.charAt(i) == '-' && (infix.size() == 0 || infix.get(infix.size()-1).equals("("))) { infix.add("0"); }

[@Naoty_san]

Remove book on top = pop (stack.pop() s.pop()) Add = push (p: stack.append(3) c++: s.push(3)) Look at the top = peek (stack[-1] s.top()) Is it empty? (stack (false, it’s empty) s.empty() (true, empty)) 6:23

guys, what this channel does...is unmeasurable. Thank you for your effort and for putting ALL this so, so valuable information online. Especially for us, self-taught :P

I'm here to learn this because I'm majoring in cybersecurity, I'm studying to become a software developer

[@notyournormaldev1419]

Cyber security is exclusive and great too man why are you leaving it.

[@tmphu]

Same question. Cyber security engineer usually earn more than a normal software engineer, and the job market is highly demanding for SEC. May you share why you leave security?

Just completed this tutorial very nice video ❤

probably one of the best stack video out there

Sir I like your teaching method

I love it, I learn new techniques everyday

Wow, just now when I am learning Dynamic Memory. Thank you for uploading this!

[@daayemshehzad]

Honestly this was such a good video tutorial. Loved it!!

[@enes5345]

Seems like you have watched it

[@daayemshehzad]

@@enes5345 yup it was a very informative tutorial

[@SelfCheckout]

noob question here, at like 17:21 there's the else case with pass if the stack is empty. Is this necessary? In my head the if statement alone should be enough and maybe you put the else case just for clarity for new programmers.

Guys what is the best book or free course to learn computer architecture?

[@random_things2023]

Thanks for that course

[@אני-ש3ת]

hey,in redundat braces, why u didnt check before the while if stack is empty?

[@lex-zt6uc]

i am still not clear about why we are adding the zero when a- is found at the start or at the start of the opening bracket ,please can someone explain it

[@organizedchaos4559]

Is there a playlist for this for each data structure?
