今天在github上找到一个用pygame做的Python游戏,但是clone到本地运行的时候却冒出了“mixer system not initialized”这样的问题.其实这句话说的就是音频混音器(具体指的就是双击右下角小喇叭图标后弹出的音量控制台)没有初始化,由于我的电脑重装过以后没有装声卡驱动,所以才导致了这个问题,安装声卡驱动以后,问题迎刃而解.…

我实在是因为无聊至极来写Div3题解 感觉我主要的作用也就是翻译一下题目 第一次线上打CF的比赛,手速很重要. 这次由于所有题目都是1A,所以罚时还可以. 下面开始讲题 A.Remove Duplicates 题目大意:给你一个序列,让你对这个序列中重复的数进行去重.要求相对顺序不变并且有限保留右边的. 首先这道题O(n)扫一遍+hash是可以的,但是这数据范围... 开桶即可. CODE #include<cstdio> const int N=55; int a[N],n,ans[N],t…
