Problem Statement

The number 105 is quite special - it is odd but still it has eight divisors.
Now, your task is this: how many odd numbers with exactly eight positive divisors are there between 1 and N (inclusive)?

Constraints

N is an integer between 1 and 200 (inclusive).

Input

Input is given from Standard Input in the following format:

N

Output

Print the count.

Sample Input 1

105

Sample Output 1

1

Among the numbers between 1 and 105, the only number that is odd and has exactly eight divisors is 105.

Sample Input 2

7

Sample Output 2

0

1 has one divisor. 3, 5 and 7 are all prime and have two divisors. Thus, there is no number that satisfies the condition.

Solution in Python (3.4.3) (judge verdict: Wrong Answer)

n=int(input())
p=[3,5,7,11,13]
x=[]
for i in range(5):
	for j in range(i):
		for k in range(j):
			if n >= p[i]*p[j]*p[k]:
				x.append(i*j*k)
cnt=len(x)
if n >= 135:
	cnt += 1
else:
	pass
print(cnt)
