Stack Abstract Data Type Stacks A stack can be compared to a Pez dispenser Only the top item can be accessed You can extract only one item at a time The top element in the stack is the last added to the stack (most recently). The stack’s storage policy is Last-In, First-Out, or...
Using linear data structures We’ve studied arrays, stacks, queues, which to use? It depends on the application ArrayList is multipurpose, why not always use it? o Make it clear to programmer what’s being done o Other reasons? Other linear ADTs exist List: add-to-front, add-to-back,...
classMinStack{public:/** initialize your data structure here. */stack<int>all_stk;stack<int>min_stk;voidpush(int x){all_stk.push(x);if(min_stk.empty()||min_stk.top()>=x){min_stk.push(x);}}voidpop(){if(all_stk.top()==min_stk.top()){min_stk.pop();}all_stk.pop();}i...
问题很简单,显然需要用stack数据结构表示。 然后只需要把上面的指令描述清楚,模拟各个指令的操作设计出5个API来完成这5个指令即可。 简单地把上面五种机器人指令描述一下: move a onto b: 先找到block a和block b所在的block stack,然后把压在a和b上面的所有block还原到初始stack(的栈顶位置)。最后把a弹出,压...

先回顾一下线性表(老师PPT截图来的) 数组:是由下标与值组成的数欧的有序结合,即其每一个元素是由一个值与一组下标所确定。 1)数组元素的值都属于同一类型 2)下标决定了元素的位置 3)每个元素下标的个数决定数组的维数 4)n维数组的每一个元素受n个线性约束 数组的结构: 数组的特点: 1)数组是多维的结构,...
