Problem Source

Luogu P1046

Problem Description

There is an apple tree in TaoTao's yard. Every autumn it bears $10$ apples. When the apples ripen, TaoTao runs to pick them. TaoTao has a $30$-centimeter stool. When she cannot reach an apple with her hand, she steps on the stool and tries again.

Now we know the heights of the $10$ apples above the ground, as well as the maximum height TaoTao can reach when she stretches her hand up. Please help TaoTao calculate how many apples she can pick. Assume that whenever she touches an apple, it falls down.

Input Format

The input consists of two lines. The first line contains $10$ integers between $100$ and $200$ (inclusive), representing the heights of the $10$ apples above the ground, separated by single spaces. The second line contains a single integer between $100$ and $120$ (inclusive), representing the maximum height TaoTao can reach when stretching her hand up.

Output Format

The output consists of a single line containing a single integer: the number of apples TaoTao can pick.
