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

. How to count off? Define a variable count log off3. Once the count is 3, what do you do with it?4. How do I get rid of a person? Place the element 05. Indicates the current or the number of people? Define the variable number;6. Because of the number of uncertain cycles, cycle conditions with Whlie numbers > 17. How to cycle off? If i = 13, go to the first person to continue the count.The code is as follows: int arr[13] ={1, 2, 3, 4, 5, 6, 7, 8, 9, ten, one, a. int count = 0, number = 13,

title: There is an int array with several numbers in it. How many different numbers are required to be counted? How often are each number appearing? The array is arranged from less to more frequency, the same frequency is from small to large. Workaround: Use an array to store different numbers and occurrence probabilities, compare the numbers in each group with the other numbers in the group, and set the same one to NULL, as well as the number of occurrences of the numbers plus 1, and finally us
