Trying to solve symmetric difference using Javascript
javascript,arrays,symmetric-difference
Here's a version that uses the Set object to make for faster lookup. Here's the basic logic: It puts each array passed as an argument into a separate Set object (to faciliate fast lookup). Then, it iterates each passed in array and compares it to the other Set objects (the...
char* string substract function throws exception
The first obvious mistake you're doing here is this: char* temp = new char[255]; temp = this->c_str(); You allocate memory then you're copying the value of a pointer. So first you're getting a memory leak and second depending on your implementation of c_str() you are copying the address of something...
Javascript program keeps outputting wrong index of array
The problem can be reduced to this: var Foo = { courses: [] }; var x = Object.create(Foo); var y = Object.create(Foo); x.courses.push(123); alert(y.courses[0]); // "123" The reason for this behaviour is that both objects inherit the same prototype and any changes made to .courses will apply to both objects....

You can create Parse class for your feed objects. After that create an array column to store objectIds of users who added your feed item to favorit. When you want to find all the objects specific user bookmarked do something like PFQuery *query = [PFQuery queryWithClassName:@"feedObjects"]; [query whereKey:@"favoritesArray" equalTo:@"YOUR USER...

You have to use ToArray() method: string[] result = "bobjoecat".SplitBy(3).ToArray(); // [bob, joe, cat] You can implicitly convert Array to IEnumerable but cannot do it vice versa. ...
Segmentation Fault if I don't say int i=0
c,arrays,segmentation-fault,initialization,int
In your code, int i is an automatic local variable. If not initialized explicitly, the value held by that variable in indeterministic. So, without explicit initialization, using (reading the value of ) i in any form, like array[i] invokes undefined behaviour, the side-effect being a segmentation fault. Isn't it automatically...
accessing range of values in arduino array
Arrays in C++ don't allow this syntax. What you should do is something like this: char[2] id; if( sx1272.packet_received.length > 5 ) { id[0] = sx1272.packet_received.data[4]; id[1] = sx1272.packet_received.data[5]; } ...
How to get range of 10 items from the arraylist in java? [on hold]
java,arrays,arraylist,pagination
You can use ArrayList.subList() giving the parameters as the start index and end index. Start index - inclusive. End index - exclusive. Exmaple - ArrayList a = new ArrayList(); a.add(1); a.add(2); a.add(3); a.add(4); a.add(5); a.add(6); System.out.println(a.subList(0,4)); It prints out - [1, 2, 3, 4] The above would print out first...
Comparing arrays with numbers in vb.net
There are a few basic ways of checking for a value in an integer array. The first is to manually search by looping through each value in the array, which may be what you want if you need to do complicated comparisons. Second is the .Contains() method. It is simpler...
