My 3-line solution uses a particular Python function. Consider the sum example again, but this time, each integer is on its line, and the first line is the number of lines that follow. For Python 3, we use PyPy version Python 3.8.13 (7.3.9+dfsg-1, Apr 01 2022, 21:41:47) with the following flags: {files}. You can run the solutions by passing the solution file to Python in a terminal like this: Most solutions need input. Here is a version of the complete solution. Problems in this category have a fixed number of lines, given in the problem Go to the problem statement on Kattis, and copy any of the sample inputs. Each Kattis problem requires data to be read from the standard input, and e.g. code golf; much to read, or there might be a special indicator solve the problem. We will then compile your code and run it on some secret input. 22.
