PAT A1051 Pop Sequence(25 分) 解题思路 按序读取所给的序列 若读入的数字大于当前栈内最大数,则逐1进栈,直到和所读数相等; 判断栈大小是否超过限制,注意此时栈顶元素不计数; 若读入的数字小于当前栈内最大数,则逐1出栈,直到栈顶和所读数相等; 若一轮循环后,栈大小超过限制或栈内仍有数字,则不能得到...
本题25 分,模拟堆栈入栈出栈过程,难度较大,考虑的细节问题比较多,核心问题是抓住哪组数据在进行比较,入栈队列、待判断的出栈队列和空堆栈之间是什么关系。 首先,新建一个空的堆栈,模拟整个入栈出栈的过程。入栈顺序与数据由入栈队列一步一步无脑给出,因此外层一个大的循环。 堆栈要与待判断的出栈队列相比较。

1051 Pop Sequence (25分) 1051 分析: 使用一个栈来模拟,将1~n依次入栈,在入栈过程中,如果入栈的元素恰好等于出栈序列当前等待出栈的元素,那么就让栈顶元素出栈,同时把出栈序列等待出栈的元素后移一位。此时如果栈顶元素还是等于待出栈元素,继续出栈。
