3.2 How would you design a stack which, in addition to push and pop, also has a function min which returns the minimum element? Push, pop and min should all operate in O(1) time. LeetCode上的原题,请参见我之前的博客Min Stack 最小栈.
stack,栈,是好比堆积木似的数据结构,从上之下堆积,取出时按"LIFO"-last int first out后进先出的规则.栈一般为线程所独有,也就是每个线程有其自有的栈,与heap堆一般为共有的不同(heap为进程所用,stack为线程所用?). stack主要有四种操作:empty判断栈是否为空:pop将栈顶的元素清除:top显示栈顶的元素(不是取走):push压栈,向栈内增加一个元素. 代码(在eclipse运行通过): .h头文件 #ifndef STACK #defin

用dart 语言实现一个简单的stack(栈).栈的内部用List实现. class Stack<E> { final List<E> _stack; final int capacity; int _top; Stack(this.capacity) : _top = -1, _stack = List<E>(capacity); bool get isEmpty => _top == -1; bool get isFull => _top == capa
