WebOther than 1, “5” has the shortest sequence for an odd number; it goes “5,16,8,4,2,1”) There is no “longest sequence” known, because takes n steps, so just take a very large power … WebFeb 18, 2024 · The 1 + collatz (...) is taking the step you just took, represented by the 1, and then adding the number of steps (calculated recursively) that the resulting number will take. For example, collatz (5) will result in the recursive method returning 1 + collatz (16) + collatz (8) + collatz (4) + collatz (2) + collatz (1) or, 1 + 1 + 1 + 1 + 1 + 0 = 5
WebFeb 2, 2024 · The Collatz sequence is formed by starting at a given integer number and continually: Dividing the previous number by 2 if it's even; or. Multiplying the previous number by 3 and adding 1 if it's odd. The Collatz conjecture states that this sequence eventually reaches the value 1. WebThe Collatz conjecture states that every such sequence will always collapse back to 1. What’s intriguing to me is that, if you replace “add 1” by “subtract 1”, the equivalent conjecture is false: 5–14–7–20–10–5-…. will cycle forever and never collapse back to 1, although 3–8–4–2–1–3-… will.
