Fastest (least execution time) approach to get max/min of an array of int without inbuilt functions except range() and len() [closed] solved Fastest (least execution time) approach to get max/min of an array of int without inbuilt functions except range() and len() [closed]
Try This: NSArray *inputArray = @[11, 45, 54, 32, 11, 56, 45, 76, 23, 87, 54, 45]; NSArray *outputArray = [inputArray valueForKeyPath:@”@distinctUnionOfObjects.self”]; Hope it Helps!! solved How to remove duplicates in an array by using only one for loop?
You delete the malloc‘ed data. You need to free it instead, or use new instead of malloc. Another bug is that you miss this line: void removeFirst(){ // If head is equal to NULL, do nothing if(head == NULL){ return; } // Store current head Node *tmp = head; // Set head equal to the … Read more
The idea is to calculate how the execution time for a piece of code – typically some algorithm, depends on the input. If a function takes N as input how long will it take to execute if N=5 or N=10. Will it take double as long? Will it take the same time? Or will it … Read more
just an example, you could pass your stack variable as an argument to the GetSum() function. private static int GetSum() { Stack<int> stack = new Stack<int>(); stack.Push(2); stack.Push(5); stack.Push(7); stack.Push(4); stack.Push(1); int sum = 0; foreach (int number in stack) { if (number % 2 != 0) { sum += number; } } return sum; … Read more
Here’s a great page to read … http://www.c4learn.com/data-structure/basic-stack-concept/ I can not take snippets from it – as it’s full of images and done in a good way to fully understand stacks and how they work. This will then allow you get to grips with the code you posted in your question. solved Stack data structure … Read more
The line vector<int> list3(list1.size()+list2.size()); creates a vector of type int and inserts list1.size()+list2.size() default contructed elements. You want to create an empty vector of type int and reserve memory for list1.size()+list2.size() elements. Use vector<int> list3; list3.reserve(list1.size()+list2.size()); solved Some problem about the algorithm of merging two lists
Here is a more efficient algorithm: For each unique number that is present in at least one of the sublists, let’s maintain a list of indices of all sublists that contain this number. This part is O(n * log n) time if we use sorting to find unique numbers or O(n) if we use a … Read more
What is the use case of the declaration of array like below in C-Language (It is valid one dont say it is error) [duplicate] solved What is the use case of the declaration of array like below in C-Language (It is valid one dont say it is error) [duplicate]
From the source-code site you can read There is small change in the code. The line min = a[i][0] + a[c][i]; should be min = a[i][c] + a[c][i]; Here is the function you’ve to change: int least(int c) { int i,nc=999; int min=999,kmin; for(i=0;i < n;i++) { if((a[c][i]!=0)&&(visited[i]==0)) if(a[c][i] < min) { min=a[i][c]+a[c][i]; kmin=a[c][i]; nc=i; … Read more
A Linked List is a data structured used for collecting a sequence of objects. The “Head” is the very first item in the sequence. The “Tail” is the last object in the sequence. Each item in the linked list (a node) will have a property called Next (and Previous if it is doubly linked) which … Read more

What you are looking for is a tagged union also called a variant. It allows you to store multiple data types at the same location just like a regular union but includes an additional but separate data member that indicates it’s type. The C++ Standard Library does not include variants but they are easy enough … Read more
Look at this code: if (a == b) { while (a == b) { ptr->next = tmp->next; tmp = tmp->next; } When a is equal to b you execute the while (a == b). Since you don’t change a or b in the body of the while, you have an endless loop. Sooner or later … Read more
