A tour of CoderPad - Go教程

- [Instructor] This course includes automated code challenges that appear when you click on the challenges link in the course table of contents. Each challenge includes instructions and a couple of code editors that you can use to create and test your own solutions to the challenge. These challenges are hosted by CoderPad and they appear in the same area of the course page where you watch the courses videos. We recommend using a desktop browser for the best experience with code challenges, but you can use the LinkedIn Learning mobile app if you prefer. The code challenge has four areas; instructions in the top left, a code editor for you to answer in the top right, another code editor where you will see how your code is used in the bottom right, and a console for output in the bottom left. You can use these drag handles to allocate space as you like. To get even more horizontal space for the code editors, you can collapse the courses table of contents on the left. Each challenge has instructions that include a description of the challenge and the challenger's parameters and desired result. Parameters are values that will be passed into your code and they have to be of a particular data type, in this case ints. The return value also has to be of a particular type and you'll see that noted in the instructions. The constraints section has useful information about the parameters that will be passed in. The examples show different parameter values and what result would be returned for each of those test cases. Create your answer in the top right code editor. There are comments in the starting code showing where to put your solution. When you click test my code, you'll see a message indicating whether your code returned a correct result. If your code isn't successful, you can ask for help. The show expected results and show hints on 10 and 11 in the top right editor, determine whether you see the expected results and any hints. Change them to a value of true to control the output. The code editor in the lower right shows how your solution is being used. You can change that code to experiment with different test cases. Regardless of whether your answer is successful, you'll see a message in the console output in the lower left. If any messages are too long to fit in that area, you can scroll sideways to see all of the text. When you've finished each code challenge, return to the course's table of contents and click the next video to see my solution.
