[Q] What are the questions about train arrival?

1.A railway station has two trains passing by, one heading south every 10 minutes, and the other heading north every 10 minutes. James needs to take the train to work every day, he has a car whenever he arrives (Anytime ). After taking the train for a year, James calculated why 91% of trains are sent to Nankai. Why? Have you ever encountered this kind of problem? Please kindly advise!

2.

An Algorithm about the number of squares? A rectangle with a height of 4 and 6 and each small square is a square. How many squares can be found at most?

 

 

 

 

A:

1 .?

2 In the gardenOpenorzWith the help of this renxiong, how can I export this n * (N + 2) formula? Use code to indicate yes

 1 public int SquareSum(int SquareWidth)
 2 {
 3         int Sum=0;
 4         if(SquareWidth!=null && SquareWidth!=0)
 5            {
 6                  for(int i=0;i<SquareWidth;i++)
 7                     {
 8                         Sum+=SquareWidth*(SquareWidth+2);
 9                     }
10             }
11           retutn Sum;
12 }

If the final result is obtained, you only need to set the width to 4 and pass in the parameter.

PS: thank you too.OpenorzBrother, freedom, sharing, and communication. I think this is what the blog Park advocates.
