will not overlap with the GI rectangle, so Gi will be deleted. This is cyclical. The three rectangles G1, G2, and G3. from X1 to X2 should be automatically terminated to prove that the overlapping rectangle exists and will not be scanned to G3.
Overall: ① merge first (time O (nlgn) ② insert and delete intervals tree and overlap (O (nlgn )).
The Code is as follows::

The three colors are complex, and the lineargradientbrush provided by gdi + is used. However, you need to calculate the diagonal length of the drawn area and divide it into three equal points based on the diagonal line.
For details, refer to the following code:
Bool ctestdlg: onerasebkgnd (cdc * pdc){Cdialog: onerasebkgnd (pdc );
// Obtain the r, g, and B values of the first color.Int r1 = getrvalue (color1 );Int g1 = getgvalue (color1 );Int b1 = getbvalue (
0 milliseconds in the case of large data volumes or small data volumes. However, the query speed for narrowing the range by date segments is no slower than the original query speed.
Clustered index is so important and precious, so I have summarized that clustered index must be built on:
1. The most frequently used field to narrow the query scope;
2. The most frequently used field to be sorted.
Conclusion:
I hope this article will not only help you in your work, but also help you understand the

Solution The result outputs a line of magnetic induction intensity curve, and all the results are stored in the result_linein.dat file, while the curve name is defined as the value of linein + nvalue, through this, we can easily distinguish the meaning of each curve. We need to observe the graph and use the plot directly.
