1F推:(若A B倒下時間差小於中間小骨牌需要的時間) Why?05/04 18:14
3F→:可輕易舉出反例吧05/04 18:14
4F→:事實上, 只要有edge相連的大骨牌, 都去做計算就可以了05/04 18:15
6F→:大於呢?05/04 18:17
8F→:另外就算等於, 最後倒下也不一定是大骨牌05/04 18:18
9F→:這題提供的第二個test data, 你把2 3 的距離改成5005/04 18:20
10F→:不就大於了嗎05/04 18:20
12F→:ohoh, 那改成 2 3 距離 2 ?05/04 18:22
14F推:事實上可以很簡單驗證,無論大於等於小於,都算並不影響05/04 18:25
15F→:答案05/04 18:25
16F→:另外如果你的演算法描述沒錯, 你就是少算了大於的部份05/04 18:25
17F→:咦, 好像不對...我想想o.o05/04 18:26
20F推:題外話...助教給個測資你都過了嗎?05/04 18:30
22F→:memset 是以 byte 為單位在設定05/04 18:40
23F→:恐怕 node[] 值並不如你想的初始為 -105/04 18:40
24F→:噗, 真的是-1 , 看來我計概要重修了05/04 18:44
28F推:隨意吧XD 另外下次發ACM文最好附上題目連結05/04 18:54
29F→:會有更多大大幫忙05/04 18:54
2F→:此函式無法運作在 windows 系統....囧05/04 08:31
3F→:想請問 windows 系統有其他辦法嗎@@?05/04 08:32
10F→:感恩!!! 馬上搜尋一下關鍵字05/05 02:00
3F推:在給 number[] 值的迴圈中, 只跑了 s=0, 就break05/02 03:29
4F→:還有看不太懂為什麼對於每個 number[s] 要給值 8次05/02 03:30
5F→: k 次05/02 03:30
4F推:不負責任猜測是1031104/27 15:53
5F→:http://acm.uva.es/p/v103/10311.html04/27 15:53
10F推:http://uva.onlinejudge.org/external/2/294.html04/28 03:32
7F推:剛開始學的時候迴圈常會少算或多算一次 要仔細想想XD04/26 16:01
1F→:while移到上面試試?04/25 02:53
2F→:假設現在一個數字都沒有, 你那個fscanf會scan到哪去04/25 02:54
4F→:那就要看txt檔裡面input格式有沒有問題了04/25 03:12
5F→:話說i應該有給初始值0吧XD04/25 03:13
7F→:檔案裡除了數字外還有 { } 跟 , ?04/25 03:21
5F推:其中一變數移到右邊,所有可能值去左邊binary search?XD04/25 01:54
6F→:以上是類似某題ACM解法-.-04/25 01:54
7F→:當然右移的是domain最大的那個04/25 01:55
8F推:判斷完degree後, 有再判斷圖是否為connected嗎 ?04/24 22:39
9F推:圖一定要是connected 才下去找尤拉迴圈04/24 23:20
10F→:試考慮一個圖有兩個components, 各有一個尤拉迴圈04/24 23:20
11F→:只判斷degree就錯了04/24 23:20
17F推:同樓上04/25 02:34
1F→:這題真的搞到頭暈 @_@04/21 18:59
2F推:這個 case l大的作法會得到正確答案, 我還在試圖證明XD04/21 19:18
3F→:還沒看懂 l大的証明 Orz04/21 19:18
2F推:嗚嗚,我已經習慣看英文變數了,中文變數看到頭昏(遮臉)04/22 11:53
