Today, I wasn’t at home. I was at Stevens University in New Jersey. So, the quality was not as usual and I had to keep the livestream shorter (solved only A-E), but it was a new format either way. I tried to show some views of New York City (which is on the other side of the river) to make up for it.

1991A — Maximize the Last Element

1991B — AND Reconstruction

1991C — Absolute Zero

1991D — Prime XOR Coloring

1991E — Coloring Game
