Type any number in the question and see what happens What is the Collatz conjecture? The Collatz conjecture is a known sequence where if a number is odd, you triple it and add 1, and if it's even you divide by 2, it's known for making a 4 -> 2 -> 1 loop where when it reaches 4, it divides by 2, and divides 2 by 2, which becomes 1, and 1 times 3 equals 3, and 3 plus 1 equals 4 so the loop keeps repeating infinitely
