◆DIFFERENT SUMS

There are some positive integers with the following properties:

-All are different and smaller than 100
-All their pairwise sums are different.

What can be the maximum possible sum of these numbers?

現有一些符合下列性質的正整數:

- 每個數都不同而且都小於100
- 任意兩個數的和都不同

那麼這些數的總和最大可以是多少?

是說這一題英文的 pairwise sum 有代表要相異嘛

By Isabella

我的意思是會考慮 2+2 的情況嗎

By Delia

如果一定要相異，翻譯可能要強調一下

By Delia

好像也不用強調就是這個意思了... 當我沒說吧@@

YOUR SCORE: 118 我崩潰了....看來今年我又要讓腎了

很好, 我是 262...這樣有一題 82%, 一題 56%, 一題 73%
結果我不是錯 56% 題是錯 73% 題到底是怎麼回事...

By Zenobia

245 now. Failed at problem 56%

By Leila

為什麼是82 56 73啊這樣不是沒有算時間的bonus point

(...顯示為還搞不懂到底為啥會錯這麼多狀態)

By Selena

you are right, should be 87 61 78 if all 5 bp includ

By Dinah

現在看著scoreboard有點疑惑我要怎麼拿118分

By Liam
at 2016-10-19T07:58

現在顯示的difficulty 怎麼跟你們寫的不一樣

By Belly
at 2016-10-22T20:51

no idea; maybe 'difficulty' is different from what
we think xd

By Dorothy
at 2016-10-23T20:15

difficulty 好像是計算回應的評價, 也就是那是主觀評分

By Franklin
at 2016-10-24T08:36

跟題目得分的答對率 (ie.客觀評價) 應該不一樣

By Thomas
at 2016-10-29T02:56

答對率本來就會波動吧

By Lucy
at 2016-10-30T08:52

我是確定我前五題的五分都有拿到, 所以 73% 是確定的

By Thomas

I still don't understand. First place is 389, and
you are 262. That means he got 127 on the problem
you failed. Isn't it possible that 127 comes from
100 + 22 (78%) + 5?

By Selena
at 2016-11-04T11:51

啊...你是對的, 所以那是 78% 才對

By Rachel
at 2016-11-08T23:03

所以正確的應該要用 205 去扣, 不是 200 去扣
