差一个测试点求调

#include<bits/stdc++.h>
using namespace std;
long long n,m,arr[100000000]={0};
deque<long long> d;
int main(){
	cin>>n>>m;
	for(int i=1;i<=n;i++)scanf("%lld",&arr[i]);
	for(int i=1;i<=n;i++){
		if(i==1){
			cout<<0<<endl;
			continue ;
		}
		if(i-1>=m and arr[i-1-m]==d.front())d.pop_front();
		while(d.size() and arr[i-1]<d.back())d.pop_back();
		d.push_back(arr[i-1]); 
		printf("%lld\n",d.front());		
	}
	return 0;
}
