@[cwcDaShuaiGe](/user/1166906) 注意：上升是保持单调上升，前项$<$后项，而不是前项+1$=$后项，还有，你看数据范围了吗？
```cpp
#include <bits/stdc++.h>
using namespace std;
int n, a, b, f[1000001], ans;
int main()
{
scanf ("%d%d", &n, &a);
for (int i = 1; i < n; ++ i){scanf ("%d", &b);if (b > a)f[i] = f[i - 1] + 1;else f[i] = 1;ans = max (ans, f[i]);a = b;}
printf ("%d", ans);
return 0;
}
```
