Dec 9th Update: I’ve made a correction to “Prize offered by” in the $289 Prize. My apologies to GASARCH and thanks for pointing out my mistake.

Note: I don’t know if these prizes have been claimed already. And if you think the challenges are dead easy, then your solutions are most likely wrong. :)
