I have a problem for you guys. If you are engrossed in Studies pls IGNORE. I repaet Do not Even LOOK AT IT. And for all the others here it goes:- Take any integer , If it is an even number then halve it, or if it is an odd number then triple it and add 1.(It means :- if n is even then n= n/2. If n is odd n=(3*n)+1.)
And I know your answer it would end like this - 4,2,1 .............. infinty.
