    --- tags: 程式研習社 --- # 程式社 程式競賽問題清單 ## 算法範例(? - zkw線段樹 : [name=Sine] - [zj_e409](https://zerojudge.tw/ShowProblem?problemid=e409) , [code](https://github.com/sinewu/algorithm/blob/master/e409.cpp) ## 未解決 - zj a981 求和問題 - [a981 problem](https://zerojudge.tw/ShowProblem?problemid=a981) , [code](http://pastie.org/p/3xnlIQYZZP4Osymw83FwUV) ![](https://i.imgur.com/cGcGyAE.png) 剩下這筆測資但找不到bug@@,想請各位幫忙QQ[name=提問者] - 找不到bug...@@ 不過可以給你當初的 [code](https://ideone.com/In0Lt8) [name=Sine] - 當輸入的數字有重複時,你的 code 會直接炸開,因為你遞迴是用「某個數字是否被取過」來判斷的,可以考慮用 index 判斷 [name=Rice] - 這題紀錄答案的方式蠻多種的,等你寫完可以看看 sine 的 code,那個是比較正常的做法。不正常但有時候會看到的做法可以看 [code](https://ideone.com/0K5qPT),也許能學到點新的想法? [name=Rice] - 不太懂Rice大大的意思,我看了一下程式碼我似乎是用index判斷沒錯,而且針對重複有多用一個tag變數記錄前一個取的人來避免重複,想問可以再詳細一點ㄇ@@? ((不敢先看兩位code所以先直接問了 [name=提問者] - 我猜應該是指#27,29吧 他的意思大概是這樣 [code](https://ideone.com/UlqwRv),不過還是錯的@@ ![](https://i.imgur.com/XlE5dx2.png) 所以繼續等通靈ㄅ [name=Sine] - 一開始的連結壞了诶QQ [name=Sine] - 好了,他只給我24hr QAQ [name=提問者] - 真是神奇=ㄦ= 還是壞的吧? [name=Sine] - 好了 拍謝QAQ [name=提問者] - 沒阿 [name=Sine] ![](https://i.imgur.com/nQXoxmJ.png) - 系統搞我啊QAQ [name=提問者] - 怕爆 [name=Sine] - 我不小心動到你上面的了拍謝OAO,位置換錯 [name=提問者] - 這串好長喔@@,解決後要來整理一下(?) [name=Sine] - 喔又抓到一個bug...你的Answer用過的東東沒歸0 [name=Sine] - 幹越來越不科學了,把最初的bug弄掉會生出另一個bug,然後解掉這個bug跟那個bug居然是衝突的= = [code](https://ideone.com/ZHZcNw) 總之就是一坨東西沒初始化,然後就炸了(? [name=Sine] - 我以為我的會自動覆蓋掉原本的ANS,難道沒覆蓋掉!? [name=提問者] - 不知道,反正先歸0再說 [name=Sine] - 我懂你的意思了大大,歸0算是保險之計(?,但我看你幫我修的code我有個問題, 為何歸0後下面要多個tag=Nums[k],這個不是沒有變化ㄇ@@?(Sor最近都沒用這個問題,就放到現在OAO [name=提問者] ![](https://i.imgur.com/RBo3PQq.png) - sine大 我拿你幫我初始化後的code再去試還是爆開在同一測資@@ [name=提問者] - 诶诶我忘記這題了QQ [name=Sine Wu] - 懶得debug了,直接給你我當初AC的[code](https://ideone.com/ZEDitD)好了 [name=Sine Wu] ## 已解決 - [TIOJ 1001](https://tioj.ck.tp.edu.tw/problems/1001) - 不知道為什麼答案錯誤 - [程式碼](https://ideone.com/gxbypg) - > 可以看一下輸出和範例輸出有沒有完全一樣[name=匿名] - > 我知道了!最後面的 "XD" 打成 "xD"[name=提問者] - > 建議以後輸出可以用複製的[name=匿名] - [TIOJ 1002](https://tioj.ck.tp.edu.tw/problems/1002) - 不知道為什麼答案錯誤 - [程式碼](https://ideone.com/EBVMoL) - >[name=yctseng] 為何你的程式碼輸出是a+a?? - >[name=匿名] 發現了,謝謝 - [TIOJ 1445](https://tioj.ck.tp.edu.tw/problems/1445) - 我用類似 DP 的方式,找到最小生成樹後把其他邊拿來改答案,WA 了一些測資 + 記憶體區段錯誤一些測資,請求 debug - [程式碼](https://ideone.com/k1hKyN) - 已解決,DP 式不小心寫錯了(一定是在睡QQ)。#42 是 `dp[j][k] = dp[k][j] = edges[i].c;` [name=Rice] - 樓上雷爆惹>_< [name=Sine]
