The accelerometer may be the most mature MEMS product, and there are many kinds of accelerometer in the market.
The commonly used accelerometer in mobile phone is Bosch (Bosch) BMA series, AMK 897X series, St LIS3X series, etc.
These sensors generally provide ±2g to ±16g acceleration measurement range, using I2C or SPI interface and MCU connected, data accuracy less than 16bit.

Note that the sorting by bit must be a stable sorting algorithm. Count sorting is often used.

Introduction to programming (Java)-1.3 separation of interfaces and Implementations
The parnas principle is calledSeparation of interfaces and implementation).I. Excerpt [P100 -]:

How to organize multiple programmers in a large team in large-scale programmingSimultaneous development, Especially how to treat the code of other programmers, frederickp. brooks Jr introduced his practice at the time (around 1964) in The Mythical
loops refer to the fact that the Code generated by the cyclic shift of a cyclic attention code is still a cyclic attention code. Redundancy refers to the use of a remainder when a cyclic attention code is formed.
The cyclic signature code is formed by attaching the signature bit after the Information Code. If the cyclic signature code is expressed as (), the length of the cyclic signature code is 7 bits, the Information Code is 4 bits, and the appended signature code is 7-4 = 3 bits.
