代码：
```cpp
#include<bits/stdc++.h>
using namespace std;
const int maxn=2e6+1;
int a[maxn];
deque<int>q;
int main(){
int n,m;
scanf("%d%d",&n,&m);
for(int i=1;i<=n;i++) scanf("%d",&a[i]);
printf("0\n");
for(int i=2;i<=n;i++){
while(!q.empty()&&a[q.back()]>a[i-1]) q.pop_back();
q.push_back(i-1);
while(!q.empty()&&q.front()<i-m) q.pop_front();
printf("%d\n",a[q.front()]);
}
return 0;
}
