为什么O(n)的单调队列也TLE???麻烦大家看一下#include <cstdio>
#include <deque>
using namespace std;
const int MAXN=1000001;
struct Node
{
int d,i;
};
int d1,d2[MAXN],n,m,num[MAXN];//d1 min d2 max
int main()
{
scanf("%d%d",&n,&m);
deque<Node> q1,q2;
for(int i=0;i<n;i++)
{
int x;
scanf("%d",&x);
Node now={x,i};
while (!q1.empty()&&i-q1.front().i>=m)
q1.pop_front();
while (!q2.empty()&&i-q2.front().i>=m)
q2.pop_front();
if (q1.empty())
{
q1.push_back(now);
d1=x;
}
else
{
Node temp=q1.front();
d1=min(now.d,temp.d);
while (!q1.empty()&&q1.back().d>now.d) q1.pop_back();
q1.push_back(now);
}
if (i>=m-1)
{
if (i>m-1)printf(" ");
printf("%d",d1);
}
//////////
if (q2.empty())
{
q2.push_back(now);
d2[i]=x;
}
else
{
Node temp=q2.front();
d2[i]=max(now.d,temp.d);
while (!q2.empty()&&q2.back().d<now.d) q2.pop_back();
q2.push_back(now);
}
}
printf("\n");
printf("%d",d2[m-1]);
for(int i=m;i<n;i++)
printf(" %d",d2[i]);
printf("\n");
return 0;
}
