[LeetCode] 622. Design Circular Queue Design your implementation of the circular queue. The circular queue is a linear data structure in which the operations are performed based on FIFO (First In First Out) principle, and the last position is connected back to the first position to make a c...
But using the circular queue, we can use the space to store new values. Implementation the MyCircularQueue class: MyCircularQueue(k) Initializes the object with the size of the queue to be k. int Front() Gets the front item from the queue. If the queue is empty, return 1. int Rear...

Take(K).ToArray();It's time complexity is O(N Log N) where N is poins.Length.But this task is actually about Heap / PriorityQue which is not implemented in C#.Using Heap time complexity is O(N Log K). So it Is better if we need only 10 points from millions as we run th...

public void pushList(List<E> objs) throws Exception; } Analysis: Here we are using some basic OS and JVM primitives to implement a blocking queue. Basically it is using monitor and lock.Javaexposes those two OS primitives to programmers as Condition and ReentrantLock. Here is the explanation ...
One implementation pitfall here is that we can not specify the answer 2D array's second dimension size to 2. If we do so, the null check logic is always false because Java auto fills 0. classSolution {publicint[][] reconstructQueue(int[][] people) { ...
Design your implementation of the circular queue. The circular queue is a linear data structure in which the operations are performed based on FIFO (First In First Out) principle and the last position is connected back to the first position to make a circle. It is also called "Ring Buffer"...
