    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

    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.

    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.
