The 3n+1 problem is a simple, interesting and unsolved mathematical problem. The problem was raised by Collatz in 1937. The Korazim problem (Collatz problem) is also called hailstone problem, 3n+1 problem, Hassealgorithm problem, Kakutani algorithm problem, Thwaites conjecture or Ulam problem. The problem is as follows: (1) Enter a positive integer n, (2) If N=1 ends, (3) if n is odd, n becomes 3n+1, otherwise n becomes N/2; (4) Moves to step (2). The special point of the Korazim problem is that
