Why doesn\'t Set.size() match the number of elements in the set\'s iterator? I\'m using a HashSet, and I added some duplicate values.Those duplicates were automatically eliminated since I used a set.
We have a class example and I just don\'t get it.I don\'t quite understand how the operator() works in this case, and everything starting with sort.I looked at the output after running the program, an
I have two files, and I want to perform some line-wise operation across both of them. (In other words, the first lines of each file correspond, as do the second, etc.) Now, I can think of a number of
I\'m trying to iterate through an array, @chem_species = [\"H2\", \"S\", \"O4\"] and multiply a constant times the amount of constants present: H = 1.01 * 2, S = 32.1 * 1 and so on. The constants are
This is a pretty straightforward architectural question, however it\'s been niggling at me for ages. The whole point of using a list, for me anyway, is that it\'s O(1) insert/remove.
I\'d like to know what is getting assigned to what in line 8. # Iterators class Fibs: def __init__(self):
In Ruby, instead of repeating the "require" (the "import" in Python) word lots of times, I do
I created a class Foo that has the method toArray() that returns an Array<Int>. Now, I have a HashMap mapping Strings to HashMaps, which map Objects to Foo. That is:
Note that the order can go either way (erase first then push back, just that this way doesn\'t require creating a local reference to the object).
In the code below, I tried iterating over the JSON object string. However, I do not get the desired output. My output on the webpage looks something like:-
