acm queue

A chain-based queue is called a linked queue. A queue is a linear table with limited operations, that is, the insertion and deletion of a queue are at both ends of the table. Therefore, two pointers are required to point to these two special locations, namely, the first pointer and the last pointer. This example uses t

Data Structure: queue and cyclic queue; Data Structure: cyclic queue Note: Yan Weimin's "data structure" (C language version) takes notes and records them for later viewing. # Include During initialization, both front and rear are equal to 0. The number of queue elements is 0. In this case, the number of

Algorithm: Use two stacks to implement a queue, complete the queue push and pop operations. The elements in the queue are of type int. "The sword means offer"The use of the stack to operate, code comments written more clearly: first determine whether the two stack is empty: Second, when the stack is empty, the stack 1 is taken out to stack two, and finally return

Data Structure Java Implementation -- queue's "wonderful" second-priority queue, java queuePreface In many cases, some data storage not only requires FIFO, but also sorting based on the priority of the data, that is, the priority must first go out, the priority of the same FIFO, in this case, the priority queue is used. Application In fact, Priority Queues are widely used. For example, the constru

1. The original question of cattle net: topic Description Xiao Ming students put 1 to n these n numbers in a certain order into a queue Q. Now he has executed the following procedure for queue Q: while (! Q.empty ()) //Queue not empty, execute loop { int x=q.front (); Remove the value of the current team head x q.pop ();

Data structure experiment queue 1: queuing for meals Time Limit: 1000 ms memory limit: 65536 K Description There were a lot of people buying meals at noon, and the dining room was too crowded. It was hard to buy a meal. The children of science and engineering were still very smart. They went straight to Zhengtong supermarket. Haha, indeed, Zhengtong supermarket also sold meals, there are several kinds of dishes, which are much better than the cante

ACM Course SummaryA semester later, this semester of ACM is I think the most difficult subject, although the most difficult, but I think the most useful or it, although did not master the four topics, but in the process of doing the exercise is very useful for thinking, and benefited. For this course summary, I will summarize from these four topics, there is something wrong in the place also hope that the t

Idea: Use Stack1 to implement the queue push operation, with Stack2 to achieve the queue of pop operations, when the Stack2 is empty, the stack1 of the data are all pressed into Stack2, waiting for the queue of pop operations. Class solution {public : void push (int node) { Stack1.push (node); } int pop () { int result; if (S

PCM (pulse code Modulation) file to ADPCM (adaptive Differential Pulse Code Modulation) file. Format Converter What we do is to convert the media format rather than the media data type. For example, the 44-khz or 16-bit audio data can be converted to 44-khz, 8-bit. The filter does not process the media data format, but still changes the audio style of the wave table. For example, the filter can be connected. A stream data and its echo. A simple ACM d

Data Structure-queue, data structure queueData Structure-queue 1. Queue DefinitionThe Queue is also a linear table with limited operations. Its operation limit is different from that of the stack. There are limits on both ends. insertion can only be performed at one end of the table (only enter not ), however, deletion

first, queue and loop queue1. Queues(1) A queue is a linear table that allows an insert operation at one end only, while a delete operation at the other end . A queue is a linear table, called FIFO, that is an FIFO (Fiirst in First out). One end of the allowed insert is called the tail of the queue, and the one end th
