When I used jquery's parents () to find the parent-level element to delete it, I found that it does not contain the root element, so I used closest (). The effect is good, but there is a difference between the two, see: amp; lt; ul amp; nbsp; class = quot; box quot; amp; nbs

age significantly, and mobile phones were prone to crashes. At that time, similar to others, Nokia and other foreign famous brand-name machines purchased had a small quality gap. One night that year, after I went to the charity concert of Andy Lau and others, I fell onto a taxi and didn't find it ...... (RMB 1650)

It may be a blow to the loss of mobile phones, or it may be because the standby time of mobile phones is a problem. We started to use an old
note Ding version of another improvement is aimed at HiFi music system, the new version of the increase of 8 Panasonic PPS audio Capacitor, further enhance the quality of purity, through the 2-level linear power supply to achieve a more powerful transient response. In the Millet note Ding version of the HiFi music system, the Millet MIUI system also rewrote the Android bottom audio drive, in addition to the built-in more than the first lossless music, sound performance low soft, as the scene.
the spirit of Blue Note price 1168 yuan, many colors are available for sale, interested friends can pay attention to see.
Motorola New Moto G (1299 RMB)
Motorola's new Moto G is also full of sincerity, first in the configuration is very mainstream, but also equipped with the Android 5.0 system, from the interface to see the original biochemistry is very high, and this is still attractive enough for And

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,

"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

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.

any of the pattern samples as the first cluster center, such as Z1 = x1
Step Two: Select the distance z1 the farthest sample as the second cluster center.
by Calculation, | | X6-Z1 | | Max, so z2 = x6
Step three: Calculate the distance between each pattern sample {XI, i =,..., N} and {z1, z2}, i.e.
di1= | | XI-Z1 | |
di2= | | XI–Z2 | |
