Strategy
交题之前先看一遍代码（数组大小，变量名，函数数组嵌套，typo）
写题之前先用算法过样例，中间过程的值记录，模拟题打表先手写好。
pre final 发生的沙雕事情记录：
wjj不要帮人抄漏抄错模板
不测样例提交 zzh *1，dyx *1, wjj *1
dyx 拒绝听 wjj 的正解（wjj 讲太快了）
dyx 给别人喂题的时候说快一点，你太慢了
边界没考虑清楚
听别人喂题之后，自己看一遍题
读题要把所有东西（input output 等）全读完才讨论
ans 的初始值
dyx 不要少取模
堆式线段树不是完全二叉树（国内定义），是完全二叉树（国外定义）。
after final 发生的沙雕事情记录：
无符号数参与比较时一定要小心，因为它会把有符号数隐式转换成无符号数。
忘记删暴力
check导致TLE取模的情况下，比如说我们要 \(dp\) 个数和和，为了加速可能在 \(dp\) 为 \(0\) 时直接
continue。这个时候一定要同时判一下个数和和是否均为 \(0\)。显然可能存在个数（取模）为 \(0\)，但是和不为 \(0\) 的情况。
