Question #38744

Question: Find all the combinations between 1 and 1000 in which
1. doubling the first number and substracting from the second number will give a result of zero.
2. if the result is not 0, double the result and use it as the first number and repeat step 1.
For example :
let us consider 7 , 8 as inputs
step 1 :
7 * 2 - 8 = 6, which is not zero, so it goes to next step and first number is 6
6 * 2 - 8 = 4, which is not zero, so it goes to next step and first number is 4
4 * 2 - 8 = 0, here it satisfies the condition so system will print 7 , 8
Another sample set that satisfies the above condition: 10, 20
10 * 2 - 20 = 0, here it satisfies the condition so system will print 10 , 20
