Rules: Do not put letters, the number 0 or more than 318 characters
If you don't know, the 3n+1 problem states that no matter what number you replace 'X' with, as long as it's positive or '0', you will eventually reach an infinite string of '421421421421...' This is the 3n+1 problem: {if n is even, X = X/2 if X is odd, n = 3x+1 repeat} This calculator will tell you how many steps/iterations it takes to go from your input to '1'
