more than 4 primary partitions for a hard disk with this type of partitioning structure.Here we need to draw out the extended partition:An extended partition is also a primary partition (Primary partition), but it differs from the primary partition in that it can theoretically be divided into countless logical partitions, each with an extended boot record (EBR) similar to the MBR structure. In the MBR partition table, up to 4 primary partitions or 3 primary partitions + one extended partition,

Problem Description:Input: Point set Q output on space plane: two closest point pairsProblem simplification: If you are looking for the nearest point pair in a straight line, you can use sorting and then find the nearest nearest point.Divided treatment ideas:Divide divides it into two parts q1,q2 T (n) = O (n)Conquer find nearest point pair Merge compare the distance between two points near the point of separation Time complexity: T (N) =o (1) n=2T (n

The worst run time for a merge sort is O (nlogn) O (N\log N). Its idea is to put two ordered subsequence, through one traversal, merged and ordered in the third sequence. Obviously the time to merge two sorted tables is linear, with a maximum of n−1 N-1 comparisons, where N is the total number of elements. The total elapsed time is deduced as follows:Suppose N is a power of 2, which always splits into two equal columns at a time. For N=1 N=1, the time of the merge sort is constant, and we are 1,

MBR (Master Boot Record)1. Master boot record, traditional partitioning mechanism, applied to most PC devices using BIOS2. MBR supports 32-bit and 64-bit systems.3, MBR supports a limited number of partitions.4, MBR only support less than 2T of hard disk, more than 2T of hard disk will only use 2T space (there is a third-party solution).5, MBR is often used for p

with the Pythagorean theorem or itself, so we can think of this as a correct way to prove it.Second, PARABOLIC(1), do not know how many people and I, in the middle school study has not been to understand the definition of parabola, then began to use. In high school, or the Xinhua dictionary tells me what is a parabola: the set of points that are equal to the point and the fixed line.For a parabolic line perpendicular to the x axis, we can make some simple inferences.Let's start with the reverse

requires constant time. When there are n>1 elements, we decompose the run time as follows:decomposition : The decomposition step only computes the middle position of the subarray, which requires constant time, so D (n) =o (n).Solution : We recursively solve two sub-problems of both scale N/2, which will contribute 2T (N/2) uptimeMerging : We have noticed that the process merge on a subarray with n elements requires O (n) time, so C (n) =o (n).When th
