Kirill plays a new computer game. He came to the potion store where he can buy any potion. Each potion is characterized by two integers — amount of experience and cost. The efficiency of a potion is the ratio of the amount of experience to the cost. Efficiency may be a non-integer number.

For each two integer numbers a and b such that l ≤ a ≤ r and x ≤ b ≤ y there is a potion with experience a and cost b in the store (that is, there are (r - l + 1)·(y - x + 1) potions).

Kirill wants to buy a potion which has efficiency k. Will he be able to do this?

Input

First string contains five integer numbers l, r, x, y, k (1 ≤ l ≤ r ≤ 10⁷, 1 ≤ x ≤ y ≤ 10⁷, 1 ≤ k ≤ 10⁷).

Output

Print "YES" without quotes if a potion with efficiency exactly k can be bought in the store and "NO" without quotes otherwise.

You can output each of the letters in any register.

其实挺水的,但是我也哇了两次.

#include <iostream>
#define ll long long int
using namespace std;
int main(){
    int l,r,x,y,k;
    cin>>l>>r>>x>>y>>k;
    for(ll i=x;i<=y;i++){
        if(k*i>=l&&k*i<=r){
            cout<<"YES"<<endl;
            return 0;
        }
    }
        cout<<"NO"<<endl;
    return 0;
}
