Practice

Try these on the judges. Each link opens the problem on WMOJ or DMOJ.

  1. 2021 S1
    Crazy Fencing (opens on WMOJ in a new tab) WMOJ

    Add up the areas of several trapezoid-shaped fence pieces, printing the exact total.

  2. 2018 J3
    Are we there yet? (opens on DMOJ in a new tab) DMOJ

    Print a small table of numbers as evenly spaced, space-separated rows.

    Why DMOJ: Tries the same kind of formatted output on DMOJ, which holds 2014 to 2020.
