Collatz Conjecture is an unsolved math problem. Type a random positive number. Then press space to calculate If the number's odd, (number) x 3 + 1 If the number's even, (number) ÷ 2 At last, the positive number will run into this loop (ANY NUMBER WILL) 4 --> 2--> 1 1 --> 4 Calculate: Press to calculate once. Fast calculate: Hover to calculate every 0.1 second Turbo calculate: Hover to calculate every delay+one block Insta calculate: Hover to insta calculate with every delay (may need a few seconds to instantly do that) For more, check youtube. Calculation time will stop if the loop is detected. It will be bugged if you type any other things that are not numbers/negative numbers.
