题意: 输入三个正整数M,N,K(<=1000),分别代表栈的容量,序列长度和输入序列的组数.接着输入K组出栈序列,输出是否可能以该序列的顺序出栈.数字1~N按照顺序随机入栈(入栈时机随机,未知在何时入栈,可能在某个栈内元素出栈以后). AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ][]; int main(){ ios::sync_with_st…

刷题 题意:栈的容量是5,从1~7这7个数字,写5个测试数据 做法:模拟栈 #include<bits/stdc++.h> using namespace std; const int maxn=1010; int a[maxn]; stack<int> st;//不用定义大小呀, //题目那也只是意味着,到那个大小你需要判断一下,并不是让你真的构造一个那么样大小的栈, //如果要是越界了还会报错,难道你还要写异常不成? int main() { int M,N,K; cin>…
