Answer to Question #38744 in C++ for Saurabh Kashyap

Question

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
