DescribeThe 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,

single-block mechanical disk available on the market now has only 10TB of storage space. When this part of the capacity is used to expand it is basically an impossible task to complete. Finally this storage method also has the security question, the single piece mechanical disk in the continuous high I/O environment is very easy to damage, as long as is a certain capital support company, the mechanical disk itself is regarded as the consumable.So even in a start-up company's online production e
