Thank you for your explanation! I just stumbled upon your channel and really like it! One thing about your algorithm regarding push n pop during open/close paran is that we should push number before sign, and pop sign before number.
Love your video. Your voice is soothing, explanation is concise and coding is very neat. Not to mention the editing out of the typing for larger chunk of code. 优秀！
Thank you so much! Can you please zoom in the web page when taking other video? Because some people use a laptop with only 13-inch screen. (such as me...)
When you pop at this point, you are guaranteed that you will get a sign, either '+' or '-', so you need to multiply that sign to your current sum to get the correct number. If you put a breakpoint and debug, you will get it.
Out of all videos explaining 224, yours is the best! Please do more of these.
agreed
I spent hours reading the explanation from Leetcode without understanding until I watched your video. You are my Leetcode savior. Nice explanation.
The best I've viewed! Explanation is precise but on point and walking through an example helps so much
i definitely love this video, no bull shit, straight to the example, nice comment, case analyst. And your pronuciation is amazing. OMG

Thanks for the video. Clear explanation!
Hi again! Can you please do a video where you solve the Basic Calculator III, that comes with all operands and parentheses?
Awesome explanation! :)
Very clear explanation
Great Explanation!
Hey it shows time limit exceed
Why do we multiply the stack.pop() * sum again?
When you pop at this point, you are guaranteed that you will get a sign, either '+' or '-', so you need to multiply that sign to your current sum to get the correct number. If you put a breakpoint and debug, you will get it.
thank you, this helps a lot
nice
讲的很好，但是由于显示器太大，所以字好小
I am a noob in Java. Could you explain what is num=num*10 +s.charAt(i) - '0' do?
Especially the +s.charAt(i) - '0' part
converts to int
You could have made the size bigger, it's difficult to see your code
