op out the numbers in the order of p, p-1, p-2, ..., 2, 1. If p is greater than m, output "error".
给定一个最多可以容纳m个数字的栈。按照1, 2, 3, ..., n的顺序将n个数字压入栈中,然后按照p, p-1, p-2, ..., 2, 1的顺序弹出数字。如果p大于m,则输出“错误”。

given a stack which can keep m numbers at most. push n numbers in the order of 1, 2, 3, ..., n and pop randomly. you are supposed to tell if a given sequence of numbers is a possible pop sequence of the stack. for example, if m is 5 and n is 7, we can obtain 1, 2, 3, 4, 5, 6, 7 from the stack, but not 3, 2, 1, 7, 5, 6, 4.
这个题目描述了一个场景:给定一个最多可以容纳m个数的栈,按1,2,3,……,n的顺序压入n个数,并随机弹出。你需要判断给定的数字序列是否可能是该栈的弹出序列。例如,当m为5,n为7时,我们可以从栈中获得1,2,3,4,5,6,7,但不能获取3,2,1,7,5,6,4。
stack.push
stack.push是栈的一个操作,用于将元素压入栈顶。在给定的代码中,stack是一个MyStack类的实例,通过调用push方法可以将元素添加到栈中。具体实现是将元素添加到数组的栈顶位置,并更新栈顶指针。例如,如果要将元素x压入栈中,可以使用stack.push(x)来实现。
