T1 up the idea did not want to abandon the 15 minutes or so, and always thought it was channel data structure that, that violence did not play too violent temporarily.
T2 will read, think there might be another hand to play for a DP nothing to harvest.
T3 will find a little feeling of nature (max-min == rl), then sd plus the sum [max] -sum [min] == sum [range], in fact, completely unnecessary.
Then think half the answer did ye think good began, sad tune for a long time ,,,,, do not find, can not two. . . Shelve buckle down T2,
See K <= 1e9, that certainly have taken mod, then shuffle that question quite a while to find loop simulation side section, so after a little timid, hand built point data can be found lying over the matter. .
then
Between T1 and T3 crazy hesitate for a moment to do this for a while doing that, the remaining 30 minutes of the time you will feel cold, I started to play violent violence had wanted to make a good ,,, no time to think anymore, mind blown up , the most violent start code
Of course, the violence ,,, test period T3 is legitimate playing pieces segment tree, finally mn ^ 2logn the complexity and play T1 ,,,,, 10 minutes through the sample ,,,, ,, cross ,, finished quickly It found that T1 burst 0, did not open long long
t3 and more maintenance prefix and 52-> 48, t280, special data card is lost, look for the simulation loop section is covered. . .
T1 start a direct wrong direction like a tree line ,,, but violence also hit collapse.
t2 did not expect the kind of energy the card out of the data (although not think it's useless)
I did not think t3 surprise, dancing and what did not expect to find. . .
Summary: the unequal distribution of time. . .
Always the last to fight violence will collapse.
Similar ideas learned to master. . To thoroughly understand the question, do not look at other people on AC anxious, of course, did not state the water white waste of time.
Do not be always thinking is limited, thought to be let go. . .
