The following data of the file data.csv is given:
Please use the following editor for your exercise. You can run the content of the editor by clicking on the tab 'Run'...
The result of running the editor content is as follows:
The output of the solution is as follows:
Please have a look at the solution only after you have finished working on your own solution. Otherwise the learn effect is much less.
