winchester serial numbers

Someone asked: Is there one ball in the bag that ranges from 1 to 10? If you want to retrieve three balls, do you have the chance that any two balls in the bag will not be connected? The invitation month took a try today. The algorithm is very general. We are looking forward to communication. The approximate algorithm is a three-tier loop. One Ball is taken out first, and then any one is taken from the remaining ball, and then ******. /// Test: Public static void main (string [] ARGs) Test res

Before the office2010 version, the method of automatically generating serial numbers was troublesome, office2010 later versions were relatively simple. Let's take the new version as an example. First we select the column to generate the automatic ordinal number. In the table tool, we can see the numbering tool. Click on the small triangle to the right of the number, we will see a number
