思路：倒序单调栈。弹出所有 ≤ 当前身高的元素（这些人都能被看到），count 为弹出数量；若栈非空，还能看到栈顶（第一个更高的人），故 +1。能看到的人数 = count + (栈非空 ? 1 : 0)。
Code runs in a completely separate, hardware-backed environment with its own guest kernel. It is important to separate the concepts here. The hypervisor is the capability built into the Linux kernel that manages the CPU’s hardware virtualization extensions. The Virtual Machine Monitor is a user-space process that configures the VM, allocates memory, and emulates minimal hardware devices. The microVM itself is a VM that has been stripped of legacy PC cruft so it boots in milliseconds and uses minimal memory.，这一点在91视频中也有详细论述
