1-5-18: Angle Valley conjecture

Describe

The so-called Angular Valley conjecture, refers to any positive integer, if it is odd, then multiply 3 plus 1, if it is even, then divided by 2, the results are repeated in accordance with the above rules, the final total can be obtained 1. For example, assume that the initial integer is 5 and the calculation process is 16, 8, 4, 2, 1, respectively.
The program requires the input of an integer that will be processed to get 1 of the process output.

Enter a positive integer n (n <= 2,000,000) to output the step from the input integer to 1, each step is a row, each part describes the calculation process. The last line outputs "end". If the input is 1, output "End" directly. Sample input

5

Sample output

5*3+1=1616/2=88/2=44/2=22/2=1end
