M3A1 Sequence

Question

so in math there's a sequence called the m3a1 sequence which is quite easy to explain, so here it goes. when a number is odd, you multiply it by 3 and add 1 to it. but when it's odd you divide it by 2 you do this until you reach 1 or -1, which you ALWAYS do.
your goal is to take input from the user, show the number's m3a1 sequence and also count how many tries it took to reach 1.
another extra thing you might like to do is find inputs that cause problems and solve them.
may the mass*acceleration be with you

Answer 2

try (-9) as input

Answer 3

@Not Found
-9, -26, -13, -38, -19, -56, -28, -14, -7, -20, -10, -5, -14... endless loop before reaching 1 or -1

Answer 4

@Not Found
i don't think it is a bug

Answer 5

@Vari93
excellent alg

Answer 6

@sayan : I didn't get the question initially. Now that I get it, I edited my code.

Answer 7

@Not Found : Check my code now. It's modified to take any input.

Answer 8

vari93 let me give an example:
let's start with 7, 7 is odd so we multiply it with 3 and add 1 so we get 22. but there is no stopping. 22 is even so we divide it by 2 . we get 11 and then 34, 17,52,26,13,40,20,10,5,16,8,4,2,1 and we are done, observe the pattern

Answer 10

thanks Randall Young. it's not a bug it's a feature. just kidding. it's a damned bug. I am starting to work on it to solve it.(after a few minutes) now it should work fine. when it's negative, I do 3n-1 so the effect is mirror of the positive side,(how I think it should be). also made it more efficient

Answer 11

@Randall Young
well now it isn't 😂😃

Answer 13

both sayan chandra and krishna's code are correct.

Answer 14

the mass is with me but not the acceleration :)

note: the question says twice odd

Answer 15

I'm a little confused. I get the part where if a number is odd you multiply it by 3 then add 1. The second part confuses me, is it if that m3a1 result is odd you start dividing it by 2 until you reach 1 or -1?

Answer 17

it works fine now 😃

Answer 18

@Not found Thank you, I will work on this when I get off work.

Answer 19

I did it in C++

oh, someone did it before me. rip.
