C 编程中,经常需要操作的内存可分为下面几个类别: 堆栈区(stack):由编译器自动分配与释放,存放函数的参数值,局部变量,临时变量等等,它们获取的方式都是由编译器自动执行的 堆区(heap):一般由程序员分配与释放,基程序员不释放,程序结束时可能由操作系统回收(C/C++没有此等回收机制,Java/C#有),注意它与数据结构中的堆是两回事,分配方式倒是类似于链表. 全局区(静态区)(static):全局变量和静态变量的存储是放在一块儿的,初始化的全局变量和静态变量在一块区域,未初始化的全局变…

题目描述 首先村落里的一共有n座房屋,并形成一个树状结构.然后救济粮分m次发放,每次选择两个房屋(x,y),然后对于x到y的路径上(含x和y)每座房子里发放一袋z类型的救济粮. 然后深绘里想知道,当所有的救济粮发放完毕后,每座房子里存放的最多的是哪种救济粮. 说明 对于20%的数据,1 <= n, m <= 100 对于50%的数据,1 <= n, m <= 2000 对于100%的数据,1 <= n, m <= 100000, 1 <= a, b, x, y &…
