用c实现运动会管理系统-used to achieve the Games Management System

在具有至少十五个节点的网络中模拟洪泛路由。每个数据包应包含一个计数器（n = 10），该计数器在每一跳上递减。(Simulate flood routing in a network with at least fifteen nodes. Each packet should contain a counter (n=10) that is decremented on each hop. When the counter gets to zero, the packet is discarded. Time is discrete, and each link can handle only one packet per time interval (i.e. only one packet in total may traverse the link in either direction). Nodes should include a buffer to queue any additional packets. Present your results in terms of the number of duplicate packets produced, and the congestion at each node, and suggest a possible solution for reducing this problem.)

说明：  提取振动曲线的波峰和波谷值，返回对应的坐标值和峰值。(extract vibration curve peaks and trough values corresponding to the coordinates of the peak value.)
