between the first half and the second half varies from person to person, or before or after. There will be a rest phase in the middle, and you can call it a halftime break. You can go to the four seas in the cloud, or leave yourself at home to leave yourself empty. Let's take a look at future strategies and methods. Do you know? There are tens of millions of ants on the tree, and the tree has a lot of forks, and finally climbed to the top of the tree, not how nice to run, not how hard to run, b

The algorithm used by the raster stream vectorization tool is primarily used to vectorize a raster of a river network or any other raster linear network that represents a known direction.The tool has been optimized to use directional rasters to help vectorize intersecting cells and neighboring cells. An adjacent raster stream with the same value of two can be vectorized to two parallel lines. This is in contrast to the raster jog Line (Polyline) tool,

There is a string of stones in a river that gives the distance between the stones, allowing you to remove the M-stone so that the shortest distance is maximum.Two-point answer, for each mid, decide whether to delete this stone.

The missionary cross-river problem is a well-known problem and often occurs in many intelligent games. However, I have never learned a general solution to such problems. I learned this topic in the AI course. As a senior student, I was no longer interested in the course. However, this problem exists in the classes I attended. However, the teacher's courseware seems to have some problems. I thought about it and thought that my idea should be correct. A
