Running result:

Experience:

After a while of thinking, he handed over the task to complete. After independent thinking and continuous debugging, no errors were displayed. This program can also be simpler and simpler. It is being modified .............

Knowledge Point summary;

When calculating the positive difference value, compare the size by programming, and reduce the value by a small margin. The result is an integer. Do not subtract the two numbers directly to avoid negative values.
