Look at the greedy algorithm today, greedy algorithm has no specific algorithm framework. The greedy algorithm mainly looks for the best solution at present, without considering the overall optimality. Only the local optimal solution is obtained.

When writing programs using STL, we often use the vector container to store data. When the data in the container is ordered, we can adopt two methods: (1) Use the find function in to search; (2) Half-lookup. In addition, you can store the

Create 1. Create a class file. Note that the directory is under classes, otherwise the file cannot be found normally. 2. Modify the pre-compilation header. If vs is used, the default value is # pragma once. For compatibility, change to # ifndef |

Because the DataGrid has a POST method, the URL can be used to post data to the specified address, so in this regard it is very similar to jquery's Ajax (I think it should be the Ajax, but I have not studied the source code of easyui in depth ).

When using the DataGrid Control of easyui, it is very easy to construct a composite header. You only need to write the column name in array mode when using the columns attribute. For example, we need to construct a header as follows: The code for
