"Overview"Karatsuba multiplication is a fast multiplication. This algorithm was presented in 1960 by Anatolii Alexeevitch Karatsuba and published in 1962.This algorithm is mainly used to multiply two large numbers. The complexity of the common multiplication is n2, while the complexity of the Karatsuba algorithm is only 3nlog3≈3n1.585 (Log3 is the base of 2)"Step " The Karatsuba algorithm is mainly used to multiply two large numbers, the principle is to divide the large number into two segment

terms of network, it supports full Netcom 2.0, dual-card dual-standby and Volte HD voice, and runs the ColorOS 5.1 system based on Android 3.0.Edit comment:As the flagship machine of OPPO for the year, OPPO R9 is not very good in hardware configuration. It is equipped with the MT6755 processor of Lianfa branch and is not a real flagship hardware machine. However, OPPO R9 has a good performance in terms of appearance design and photo taking. It is impressive in terms of the fast-charging experie

Idea: open a four-dimensional array record. Note that the initial position of the two persons must be set to "." Open Space.
Originally, I opened two 3D arrays at the beginni
The distance between two triplet (x1, Y1, Z1), (X2, Y2, Z2) is defined as follows:
D = max {x1 −x2, Y1 −y2, Z1 −z2} −min {x1 −x2, Y1 −y2, Z1 −z2}
Now we will give you n triplet, so that you can find the sum of the distance between any two triplet.
Question: formula conversion is very useful and must be taken seriously.
First, simplify the model:
Make a = x1-x2,

In the figure, R1 and R2 are common resistance with a resistance of 10 euro. Their function is to prevent the generation of an over-current burned-out chip when the RS485 signal D + and D-short circuit are used. Z1 and Z2 are the 6 V clamping voltage, zonea diode with a maximum current of 10A. The 24 V power supply and the 5 V power supply are not isolated.

Step three: Calculate the distance between each pattern sample {XI, i =,..., N} and {z1, z2}, i.e.
