Definition of the Fibonacci sequence (Fibonacci sequence) : The Fibonacci sequence refers to such a sequence 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233,377,610,987,1 597,2584,4181,6765,10946,17711,28657,46368 ..., this series begins with the 3rd item, each of which equals the sum of the first two. The Fibonacci sequence, also known as the Golden Section sequence, was introduced by the mathematician Leonardo's Fibonacci (Leonardoda Fibonacci) as an example of rabbit breeding, which is called

Recently in the development needs a function, to the third-party server to send our data, the package format requirements of the data is particularly strict, after the completion of the assembly data, sent to the third party server but how can not pass, looked for a long time, also compared to the other side of the data samples, or not, Later check the code and intercept the sent data only found that when the socket is sent, using the println () method, this method will automatically add a carri
