神盾盃2023初賽

[23/10/23 更新]: 賽後有和沛凡和asef討論這個題目，終於知道問題出在哪邊，當我們解出$m^3$時，要記得$mod\ n$，然後找到$m$的方式就是暴力搜，暴力搜得意思是因為我們拿到的$m^3$其實是$mod\ N$的結果，代表要找到真正的flag可能要再加上數個$N$才會是原本的flag，也就是$flag \equiv m^3\ (mod\ N)\to flag=k\cdot N+m^3 k\in \mathbb{Z}$，所以我們只要暴力找到那個$k$使得$m^3$開三次方根是整數就代表我們找到真正的flag了

VirtualBox滑鼠無法跳出

Problem Description

在VirtualBox中如果滑鼠無法跳回本機，請先按照其他blog提出的solution自行排除123，如果暫時找不到解決辦法，也可以參考4的做法，Ctrl+Alt+Del強制本機電腦跳出windows選項，此時滑鼠的控制權就會交回到本機端

  1. VirtualBox中鼠標在主機和虛擬機之間切換 ↩

  2. 在Windows虛擬機中安裝Virtualbox增強功能 ↩

  3. oracle vm virtualbox 怎麽讓鼠標出來啊？  ↩

  4. [VirtualBox] windows下解決移除Host鍵後VM滑鼠無法移出  ↩
