错的挺多，数组开小了，sum也不是一直累加的，需要更新，sum初值应为1

```
#include <bits/stdc++.h>
using namespace std;
const int N=1e6+10;
int a[N], ans;
int main(){
int n,sum=1;
cin>>n;
for(int i=1;i<=n;i++){
cin>>a[i];
}
for(int i=1;i<=n;i++){
if(a[i]>a[i-1]){
sum++;
}
else
sum = 1;
ans = max(ans,sum);
}
cout<<ans;
return 0;
}
```
