Problem Statement :

Given two integers a and b. Your task is to find the sum of all the even divisors of each number from a to b inclusive. Input The input contains two integers a and b.

Constraints:- 1 ≤ a ≤ b ≤ 108 Output Print the sum of even divisors. Example Sample Input 1:- 1 10

Sample Output 1:- 38

Sample Input 2:- 1 20

Sample Output 2:- 148

Explanation: Even divisors for 1:- NIL Even divisors for 2:- 2 Even divisors for 3:- NIL Even divisors for 4:- 2, 4 Even divisors for 5:- NIL Even divisors for 6:- 6 Even divisors for 7:- NIL Even divisors for 8:- 2, 4, 8 Even divisors for 9:- NIL Even divisors for 10:- 10 Total :- 2+2+4+6+2+4+8+10 = 38
