@[Oak_limy](/user/25871) 我不懂时间复杂度，不过我懂了，大概是我判断太多次了
刚改了一下，AC了
```cpp
#include<iostream>
#include<cstdio>
using namespace std;
int n,up,ans;
int main(){
scanf("%d",&n);
int day[n];
for(int i = 0;i < n;i ++) scanf("%d",&day[i]);
up = 1;
for(int i = 0;i < n;i ++){
if(day[i + 1] > day[i]) up ++;
else up = 1;
if(up > ans) ans = up;
}
printf("%d",ans);
return 0;
}
```
