See here for SetRoom and GetRoom methods that do not use arrays. Using GetRoom and the individual int member variables Room1 to Room4 you can find the room with the maximum number of bottles like this: int maxValue = Room1; int maxRoomNumber = 1; for (int i = 2; i <= 4; i++) { int … Read more
A simple for loop should be able to do this: for (x in i_array){ iv[ii_array[x]] = i_array[x]; v[iii_array[x]] = i_array[x]; } See jsfiddle here. UPDATED TO SOLVE REAL PROBLEM Your code was messed up in a few places. See working jsfiddle here. First of all, you don’t need to create new arrays. Just use the … Read more
but can that iterator be converted to char array ? Yes Iterator#next() will give you string (because List has generic type String) that can be used to perform any kind of string operation. See the code below put it in main method and run. String[] str = {“Sam”, “Mohit”, “Laksh”, “Nitesh”}; List<String> list = new … Read more
NumberOfStrings++ is outside of your for loop when you read (i.e. it only gets incremented once). Also please consider using std::vector<std::string> instead of a dynamic array. Here’s a version of your code using std::vector instead of an array: #include <vector> #include <fstream> #include <iostream> #include <string> class StringList { public: StringList(): str(1000000), numberOfStrings(0) { std::ifstream … Read more
OK, here’s my answer, which should be O(N*N) worst case. (With smaller constant, since even worstcase I’m testing N against — on average — 1/2 N, but this is computer science rather than software engineering and a mere 2X speedup isn’t significant. Thanks to @Alexandru for pointing that out.) 1) Split cursor (input and output … Read more
You can define the table size and print the multiplication grid as follows: public static void main(String[]args) { final int TABLE_SIZE = 12; // Declare the rectangular array to store the multiplication table: int[][] table = new int[TABLE_SIZE][TABLE_SIZE]; // Fill in the array with the multiplication table: for(int i = 0 ; i < table.length … Read more
Arrays are used to store primitive values and objects. For example, we can create an array of String or any class objects. To explain, Lets create a class Employee containing a single instance variable empId. Following is the definition of this class. class Employee{ int empId; } An array of objects is created just like … Read more
You can simlpy cycle through the second array, split at :, check the first part and, in case of a match, return the second function findX(value, arr) { for (var i = 0; i < arr.length; i++) { var toSplit = arr[i].split(‘:’); if (toSplit[0] === value) { return toSplit[1]; } } } console.log(findX(“User1-2”, [“User1-2:280”, “User2-2:280”, … Read more
It sounds like you want to group the items by league. Let’s use our array_reduce friend for that. This is the basic syntax: $arr = [ [ “leauge” => “sweeden”, “fixture” => “12” ], [ “leauge” => “sweeden”, “fixture” => “13” ], [ “leauge” => “germany”, “fixture” => “14” ], [ “leauge” => “france”, “fixture” … Read more
Try to add a for loop to calcolate the sum of ages like this: for(i=0;i<age.length;i++){ sum+=age[i]; } And take out this below block out of for loop: avg= sum/age.length; System.out.println(“the avarage of all Students are :”+avg); System.out.println(“the minimum age of all Students : “+min); Like this: public static void main(String[] args) { // TODO code … Read more
Stride is usually reported in bytes, not pixels. Each pixel is 4 bytes (32 bits). This means that your offset or padding will be 0 (2048 bytes – 512*4 bytes). Each row of your bitmap will be 512 * 4 = 2018 bytes, and there will be 512 rows. This means that it is simply … Read more
As per @EmilioPelaez I did not use NSTimer directly: NSUInteger frameTicker =0; -(void)someMethod: (NSTimer*)t{ frameTicker++; NSMutableArray *subArray = [dataPoints objectAtIndex:frameTicker]; } I would give him credit, but he did not post an answer. solved Convert NSTimer to NSUInterval for Array Index
Introduction Java is a powerful programming language that can be used to solve a variety of problems. One such problem is getting the difference between two arrays. This can be done in a few different ways, depending on the type of data in the arrays and the desired output. In this article, we will discuss … Read more
First you would need to make a method in your custom class that accepts an object of the same class and tests whether the imputed object has the same values as the object which is calling the method. Then just loop through the array and see if the object is equal to another object. This … Read more
A structValue{}; is aggregate initialization, so 0 are guaranteed. As A has no user provided constructor because explicitly defaulted constructors do not count as such, the same applies for value initialization as in A* psstructValue = new A();. For the default initialization cases: Reading uninitialized variables is UB, and Undefined behavior is undefined. The compiler … Read more
