"Cannot read property 'length' of undefined"报错处理
数据绑定在刚开始只是和内存建立联系，并没有真正的和后台的数据挂上钩，所以一开始的res.data只是一个空值，必须在之前加个if判断，确保有值以后再开始计算length。 if(res.data){ this.num = res.data.length; } 这样就不会在控制台显示报错了。 ......

https://codeforces.com/contest/1864/problem/C 思维越来越僵化了 假如\(n=2^k\)，直接每次/2就行。 否则，我们可以考虑如何转化成上面的情况 令\(n=2^k x\)，那么我们显然可以转移到\(n=2^k (x-1)\)，因为x是奇数，所以2的次幂 ......

来道喜闻乐见的DS题，这题虽然比较套路但还是挺有趣的 一个朴素的想法就是用类似于珂朵莉树那样的方式维护所有内部等级相同的区间，但当操作数量上去后，显然分出的区间数量就变得不可控了，无法处理 另一个朴素的想法就是对于不同等级的龙维护它们的所有信息，直接暴力记录的话肯定不行，但考虑到操作的方式是从\(x ......

CF1894B Two Out of Three
思路 简简单单构造题，就是要认真读题，是能且只能满足两个条件。 我们可以考虑每种数字，如果数字只有一个，是不能满足任何一个条件的，那就随便给一个 \(b\) 即可。 如果这个数字有多个，那么就只能有两种 \(b\)，否则就会满足三个条件，所以一种数字最多满足一种条件。 所以，如果只有一个或者甚至没有 ......
