Simply, the difference is that Object is a single object whereas Object[] is an array (multiple or collection) of indexed objects. For example you could have an object that contains a string like Object obj = “Hello”; or you could have an array of strings like Object[] objArray = new Object[2]; objArray[0] = “Hello,”; objArray[1] … Read more
In Java you only have primitive or references to objects.* int[] arr = { 1, 2 }; int i = arr[0]; assert arr instanceof Object; // true arr is a reference to an array which has int as a element. how it was achieved? int[] has it’s own class int[].class and your arr is an … Read more
You have syntax issue as @eyllanesc pointed. Just change it to this, it will be fine: sum = 0 for t in range(1000): if t % 3 == 0 or t % 5 == 0: sum += t print(sum) solved Project Euler Problem #1 – Not getting the right answer
Loop for( statement expression; action ) body loop is just a while loop { statement; while ( expression ) { body label_for_continue: action; } } So you can see that everything declared inside will have its life ending outside of for. You can use break to stop loop prematurely and continue to jump back to … Read more
you forgot to add ‘\0’ char in zero terminated char array, after you replaced value with index 2. 1 solved Assigning char array from ifstream breaks array if adding another char to array
% is remainder operator. It gives the remainder after division. Quoting from MDN The remainder operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend, not the divisor. It uses a built-in modulo function to produce the result, which is the integer … Read more
some how I achieved it in lengthy way …Not sure if any shortcut is there to achieve… var keywords_updated = (keywords.Replace(” “, “* “)); keywords_updated = keywords_updated.EndsWith(““) ? keywords_updated : keywords_updated + ““; MatchCollection col = Regex.Matches(keywords, “\\”(.?)\\””);//Regex.Matches(keywords, “(?<=\”)[^\”](?=\”)|[^\” ]+”); var data = col.Cast().Select(m => m.Value).ToList(); Console.WriteLine(data.Count); foreach (var item in data) { keywords_updated = … Read more

Lisp has cond which Wikipedia’s source places in the 1956-1958 timeframe. I invented conditional expressions in connection with a set of chess legal move routines I wrote in FORTRAN for the IBM 704 at M.I.T. during 1957-58…A paper defining conditional expressions and proposing their use in Algol was sent to the Communications of the ACM … Read more

std::sort: The comparison object expected by it has to return true if the first argument is less than (i.e. is ordered before) the second. strcmp, the function you provided has another return convention: Negative value if lhs is less than rhs. 0 if lhs is equal to rhs. Positive value if lhs is greater than … Read more
After you look into documentation for charts a bit more, you would probably for example if you make a line chart LineChartView() you can have different update functions to change how it looks, for example here is one of mine: func lineChartUpdate(dataPoints: [String], values: [Double]) { //Graph data management var lineChartEntry = [ChartDataEntry]() for i … Read more
Do you really mean a swarmplot with several hundred thousand points? Besides it’s gonna take forever, it’s nonsense. Try with the first 1000 and see what kind of mess you get. Then use a boxplot or a violinplot instead. Try to understand your tools before using them. From the docstring: […] it does not scale … Read more
The reason is your updateQuantity is having the productRow being defined such as: var productRow = (quantityInput) .parent() .parent(); var price = parseFloat(productRow.children(“.product-price-l3”).text()); Which in turn make the price unable to be defined properly. If you change them into: var productRow = $(quantityInput).parent().parent(); it would work. Also if you want to give space between h1 … Read more
