Now we know  101 The height of an apple to the ground , And the maximum height that can be reached when the handle of pottery is extended , Please help Tao Tao calculate the number of apples she can pick . Suppose she ran into an apple , The apple will fall .

Input format

The input consists of two lines of data . The first line contains  10  individual  100  To  200 Between （ Include  100  and  200 ） The integer of （ In centimeters ） respectively  10 The height of an apple to the ground , Two adjacent integers are separated by a space . The second line only includes one  100 To  120 Between （ contain  100 and  120） The integer of （ In centimeters ）, It means the maximum height that can be reached when the handle of pottery is extended .

Output format

The output includes a line , This line contains only one integer , The number of apples that pottery can pick .

Input and output

Input

100 200 150 140 129 134 167 198 200 111
110

Output

5

Examine the subject ： Take turns typing 10 Apple height , Then with Tao Tao's height +30 Compare , If it is less than , Just res+1.

step ：

1. Defining variables

int a[15],n,ans=0;

2. Enter the apple height

for(int i=1;i<=10;i++)
{
	cin>>a[i];
} 

3. Enter the height 、 Compare

cin>>n;
for(int i=1;i<=10;i++)
{
	if(n+30>=a[i])
	ans++;
}

Output ：

cout<<ans<<endl;

Complete code ：

#include<iostream>
using namespace std;
int a[15],n,ans=0;
int main()
{
	for(int i=1;i<=10;i++)
	{
		cin>>a[i];
	 } 
	cin>>n;
	for(int i=1;i<=10;i++)
	{
		if(n>=a[i] || (n+30)>=a[i])
		ans++;
	}
	cout<<ans<<endl;
	return 0;
}

Novice , I would appreciate your comments.
