Hey!!!!
Can anybody tell me some refference for C/C++ .
same names for the days of the week in Filipino
It seems the Map needs to be changed to HashMap
Your voice! so Amazing. love it
To be honest I don't know what is the quality of your teaching but your voice is sexy
singing.. ahhaaa
hey! can we retrieve a key if we know its value?
Please answer
Just out of curiosity, are you big fan of Bucky Roberts(thenewboston)?
oooo, sep2
My job-interview:
who taught you JAVA?
Me: some blondie in Internet.
What?
Published on Jan 8, 2016 But u still hv a huge response for these videos (from 2019)
Can i have the project files?
Thank you very much! I learned much from your video.
I really love your voice and the way you teach us…😍💓💗
Surely you have excellent teaching spirit!.
Is a map the c++ equivalent of this?
I really love how you explain things <3
A computer science video with a clear and simple explanations, enthusiasm and in American English?! too good to be true!
You could use this to make a word to definition dictionary correct?
you voice irritates me but the video was good..
Java is ok, but spanish looks weird
This is how students should be taught, 1st video I Saw at Hackrnk and just splendid, literally MZA AA GYA 🙂
I'm not agree with what you said that there is no garantee order in Java Dictionary. Hashmap doesn't garantee the order but LinkedHashMap does. Here is more information https://stackoverflow.com/questions/683518/java-class-that-implements-map-and-keeps-insertion-order
Thank you
One of the very good explanation about Hashmap..Saying simple as possible with cheerful manner 🙂
Why americans need know Spanish? Latinos? DAMMMMMMM i hate dam
Whats the difference between maps & hashmaps?
Why don't you use c++ instead of java?
i don't understand java. Please help me
wohooo yeah its weekend XD . awesome teaching skills.
and how to impleent it on GUI when input text in textfield press button and it returns you value of this key? it wil be nice if you make tutorial on this topic
It was fun watching the video.
Your are funny ; )
Thanks
Everyone has told about your videos already, lemme now add one more – Your voice is really melodious. I got attracted to you. LOL.
I didn't understand why boolean didn't work and Boolean worked……………..the same thing happened when i tried entering 'int', it didn't work but it worked with "Integer"
Thanks in advance 🙂
1) Hi, I am currently working on the Meeting Overlap problem which I am trying to do with HashMaps, however instead of taking the number of test cases and then inserting the start and end time, if I want to develop a program to take any number of testcases i.e directly start putting the start and end times and want the program to tell me if it overlaps or not, then what should be the way to go? This is a basic question which I didn't think of, don't know why, however got rejected at the last round in one of the valley companies at the last phase of optimization because of this, so currently obsessed with it, any help would be appreciated. So formulation my question, it doesn't have to do with just this specific problem, think of it in any scenario, even a prime number, if I start putting the prime numbers right away and want the program to give me the result, however the condition is that it cannot take how many number of prime numbers I want to check for primality.
2) In the Meeting Overlap problem, while comparing, one of the comparisons will have to be comparing the key of the inserted set to the value of its previous key, how to establish it? Can we get the key somehow, as usually I only know how to get the value, if any of other like queue works for this problem, I would surely like to know about it, however I want to know how to work with it in hashmaps as well.
Any input is appreciated.
So, say I go " public String getStory(){ "
does it matter if there is a space after the () before the {? the default seems to be a space. Is it going to screw anything up if I don't use a space in more complicated code? It seems kind of pointless to add a space if you don't need one.
Keep being awesome 🙂
I love your commentary! If I was taught programming like this it would be so cool! Thanks a ton!
Oh My God – Thank you this make SOOOOOOOOOOOO much more sense
5:44 – For the other pedants in the audience, on PC (Windows) you can type the accented 'e'/é by typing Alt+0233 on the numpad (not the the top number row), and 'a'/á is Alt+0225.
