HAHA! Got it!
With some Mathematica help on solving summations. I managed to see the ‘easy’ pattern everyone talks about in the forum that gets unlocked upon solving it! Boy I really over did this one
(4 a^2 (2 + b) + a (b (9 + 5 b – 5 c) – 8 c) -
3 b (2 + b) c + (4 a – 3 c) (-2 + a – Mod[b, a]) M [...]
Oh man! I had it. If only I was as fast as these guys to the left!
I got short and long for the 1st problem (but almost everyone did).
I was so close to finishing the second one, (I would have had to get the long set as well at that point in the competition to make the top 1000).
Don’t know if I want to try at 2am my time the round 1C [...]
Hmmm… Google code jam really took it to me in Round 1A. I thought I would be clever and use strategy to get into the top 1000.
I knew my strengths and weaknesses.
Weakness- only a month of programming experience and in Python (which doesn’t execute as fast as C++), so speed is not my friend
Strength- problem solving ability
So, a [...]
All I had to do was find the number of elements out of place!! I actually thought I tried that! GCJ
Well, I got 3/4 problems correct. On one of them I didn’t get the Long data set because I didn’t realize I could only try once so I had not yet optimized my code (I thought I could gauge how much optimization I would requir [...]
