PROBLEM:
You have A notebooks, with B pages each.
You can write 50 lines on the front and 50 lines on the back of each page.
How many lines can you write in total?
EXPLANATION:
With 50 lines on the front and 50 lines on the back of each page, that’s a total of 100 lines that can be written per page.
Each notebook has B pages, so you can write 100\times B lines per notebook.
With A notebooks in total, multiply that quantity by A to obtain the final number of lines:
100\times A\times B
TIME COMPLEXITY:
\mathcal{O}(1) per testcase.
CODE:
Editorialist's code (PyPy3)
