设备数+1，time+1

代码

class Solution {
public:
    int countTestedDevices(vector<int>& batteryPercentages) {
        int time = 0;
        int ans = 0;
        for (auto &i:batteryPercentages)
        {
            if (i - time > 0)
            {
                time++;
                ans++;
            }
        }   
        return ans;
    }
};
