只是想動動腦

是說這一題英文的 pairwise sum 有代表要相異嘛
09/03 00:50, 3F

09/03 00:51, , 4F
我的意思是會考慮 2+2 的情況嗎
09/03 00:51, 4F

09/03 00:53, , 5F
如果一定要相異,翻譯可能要強調一下
09/03 00:53, 5F

09/03 00:56, , 6F
好像也不用強調就是這個意思了... 當我沒說吧@@

有點不太懂qq
09/03 17:14, 7F

沒事啦,只是數學病發作,都說當我沒說了XD

YOUR SCORE: 118 我崩潰了....看來今年我又要讓腎了
09/05 21:23, 10F

09/06 10:04, , 11F
很好, 我是 262...這樣有一題 82%, 一題 56%, 一題 73%
09/06 10:04, 11F

09/06 10:04, , 12F
結果我不是錯 56% 題是錯 73% 題到底是怎麼回事...
09/06 10:04, 12F

09/06 11:10, , 13F
245 now. Failed at problem 56%
09/06 11:10, 13F

09/06 11:41, , 14F
為什麼是82 56 73啊 這樣不是沒有算時間的bonus point
09/06 11:41, 14F

09/06 11:43, , 15F
(...顯示為還搞不懂到底為啥會錯這麼多狀態)
09/06 11:43, 15F

09/06 11:49, , 16F
you are right, should be 87 61 78 if all 5 bp includ
09/06 11:49, 16F

09/06 11:57, , 17F
現在看著scoreboard有點疑惑我要怎麼拿118分
09/06 11:57, 17F

09/06 11:58, , 18F
現在顯示的difficulty 怎麼跟你們寫的不一樣
09/06 11:58, 18F

09/06 12:20, , 19F
no idea; maybe 'difficulty' is different from what
09/06 12:20, 19F

09/06 12:20, , 20F
we think xd
09/06 12:20, 20F

09/06 13:57, , 21F
difficulty 好像是計算回應的評價, 也就是那是主觀評分
09/06 13:57, 21F

09/06 13:58, , 22F
跟題目得分的答對率 (ie.客觀評價) 應該不一樣
09/06 13:58, 22F

09/06 16:01, , 23F
答對率本來就會波動吧
09/06 16:01, 23F

09/06 17:56, , 24F
我是確定我前五題的五分都有拿到, 所以 73% 是確定的
09/06 17:56, 24F

09/08 12:16, , 25F
I still don't understand. First place is 389, and
09/08 12:16, 25F

09/08 12:16, , 26F
you are 262. That means he got 127 on the problem
09/08 12:16, 26F

09/08 12:16, , 27F
you failed. Isn't it possible that 127 comes from
09/08 12:16, 27F

09/08 12:16, , 28F
100 + 22 (78%) + 5?
09/08 12:16, 28F

09/08 19:24, , 29F
啊...你是對的, 所以那是 78% 才對
09/08 19:24, 29F

09/08 19:25, , 30F
所以正確的應該要用 205 去扣, 不是 200 去扣
