Earlier quoted context omitted.
Because I'm a ICPC medalist (not this year though) but not a IOI medalist. Another evidence is that you only have 5 hours to solve 3 problems in IOI, but you need to solve 10+ problems in ICPC. It's impossible to have all 10+ problems to at IOI level in ICPC.
> Because I'm a ICPC medalist (not this year though) but not a IOI medalist. Isn't getting a medal a function of your ranking, not score, in both cases? If so, that does not prove much about the difficulty of either.
Yes, medal is function of ranking but not difficulty.
Nonetheless, I would say that IOI more focus on thinking, which I to some degree is not that good at, while ICPC is more like a mix thinking and implementing. Therefore, my ability to implement stuff can improve my ICPC ranking but not IOI.
