模拟栈的过程,一开始我是用的cin来判断每行的每一个数字,然后判断回车结束.有一个点会超时,答案用数组先记录序列的方法非常好.有一个注意点就是访问s.top()的时候先要保证s.size()>0,这点和数组是一样的. #include<bits/stdc++.h> using namespace std; int m,n,k; ]; int main() { stack<int>st; scanf("%d %d %d", &m, &n, &…

题目描写叙述 Given a sequence of positive integers and another positive integer p. The sequence is said to be a "perfect sequence" if M <= m * p where M and m are the maximum and minimum numbers in the sequence, respectively. Now given a sequence a…

1051. Pop Sequence (25) 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…

1140 Look-and-say Sequence (20 分)   Look-and-say sequence is a sequence of integers as the following: D, D1, D111, D113, D11231, D112213111, ... where D is in [0, 9] except 1. The (n+1)st number is a kind of description of the nth number. For example…

Look-and-say sequence is a sequence of integers as the following: D, D1, D111, D113, D11231, D112213111, ... where D is in [0, 9] except 1. The (n+1)st number is a kind of description of the nth number. For example, the 2nd number means that there is…
