Given 5 integers K, L, R, X, Y. Find whether there exists two integers A and B such that A / B = K where L ≤ A ≤ R and X ≤ B ≤ Y.

Example 1:

Input: K = 1, L = 1, R = 10
       X = 1, Y = 10
Output: 1
Explanation:
A = 1 , B = 1 exists such that L ≤ A ≤ R,
X ≤ B ≤ Y and A / B = K.
Note,there are other pairs present
Like A = 2, B = 2 etc which also satisfy 
the conditions.

Example 2:

Input: K = 1, L = 1,  R = 5
       X = 6, Y = 10
Output: 0
Explanation:
No such A and B exist that  satisfy all 
the conditions.

Yout Task:
You don't need to read input or print anything.Your Task is to complete the function easyProblem() which takes 5 integers K, L, R,  X and Y as input  parameters and returns 1 if there exists two numbers that follow above given conditions. Otherwise return 0.

Expected Time Complexity:O(N)
Expected Auxillary Space:O(1)

Constraints:
1≤ K, L, R, X, Y≤ 10⁶
