a bad implementation using linked list where you enqueue at head and dequeue at tail would be O(n) because you'd need the next to last element, causing a full traversal each dequeue enqueue: O(1) (amortized, linked list and array [probing]) dequeue: O(1) (linked list and array) emp...

Thanks to everyone who contributes to this, make sure to see CONTRIBUTING.md for contribution instructions! 4 hours ago MalwareSourceCode 6316 Collection of malware source code for a variety of platforms in an array of different programming...
In the Linux kernel the PID is represented as a structure. Inside we can also find the namespaces a process is part of as an array ofupid struct. structupid{intnr;/* the pid value */structpid_namespace*ns;/* the namespace this value* is visible in */structhlist_nodepid_chain;/*...
Imbalanced array (CF Educational Round 23)Same as the previous problem, but choose a random ofN·(N + 1) / 2intervals. Bonus: Do it inO(N)if the input contains a permutation of numbers1throughN. Randomizer (CF 313 D)You're given a convex polygon withNvertices (N ≤ 20...
heapify - create a heap from an array of elements, needed for heap_sort heap_sort() - take an unsorted array and turn it into a sorted array in-place using a max heap note: using a min heap instead would save operations, but double the space needed (cannot do in-place). Tries No...
Will not implement. Implementing with the array is trivial Queue dequeue() - returns value and removes least recently added element empty() full() Cost: a bad implementation using a linked list where you enqueue at the head and dequeue at the tail would be O(n) because you'd need the ...
If you can already program using another language, you can probably learn JavaScript in a few hours. You’d be able to create a skeletal website or mobile application and get things running. It will take you a few weeks to get more familiar with the packages or ...
A hash map uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found. Collision Resolution Separate Chaining: in separate chaining, each bucket is independent, and contains a list of entries for each index. The time for hash map...
budgeting app. The first thing you could figure out how to do would be to calculate the current balance of an account. Assuming you have the value of each transaction stored in an array, you could write a script that sums all the elements of the array together ...
Implement a vector (mutable array with automatic resizing): Practice coding using arrays and pointers, and pointer math to jump to an index instead of using indexing. New raw data array with allocated memory can allocate int array under the hood, just not use its features ...
