ZeroJudge B138: Picking Apples

In Tao-Tao's backyard, there is an apple tree that bears 10 apples every autumn. When the apples are ripe, Tao-Tao goes to pick them. Tao-Tao has a 30-centimeter-high stool. When she can't reach the apples directly with her hands, she stands on the stool to try again.

Now that we know the height of the 10 apples above the ground and the maximum height Tao-Tao can reach with her hands extended, let's calculate the number of apples she can pick. Assuming that when she touches an apple, it falls down.

Sample Inputs/Outputs

Thought Process

Because there's a 30-centimeter-long stool, you can subtract 30 centimeters from the input apple heights. Then, you can simply check if each height is less than or equal to the maximum height Tao-Tao's hand can reach.

#include <iostream>
#include <vector>
using namespace std;

int main() {
    cin.sync_with_stdio(0);
    cin.tie(0);
    vector<int>num;
    for (int i = 0; i<10; i++)
    {
        int tmp;
        cin >> tmp;
        tmp -= 30;
        num.push_back(tmp);
    }
    int height, ans = 0;
    cin >> height;
    for (int i = 0; i<10; i++)
    {
        if (height >= num[i]) ans++;
    }
    cout << ans << "\n";
}
