If the n-digit number 22…22 is divisible by 9, find the smallest possible value of n.

若n位数22…22可被9整除，求n的最小可能值。

Justify the correctness of the recursive division algorithm given in page 15, and show that it takes time O(n^2) on n-bit inputs.

证明15页递归除法算法的正确性，然后证明对于n位输入，他需要O(n^2)的时间。

Adjacency search, double linked element list, random direction search, adjacency rotation, and heredity of geometrical quantities are applied to increase the efficiency of mesh generation. The relationship between the computing time and the number of generated elements is nearly linear and the time complexity is O(N^1.05), where N is the number of elements.

采用了邻接单元搜索、双向链表存储、随机方向搜索、邻接旋转、几何量继承等技术，使算法的计算时间与生成单元数近似呈线性关系，时间复杂度达到O(N^1.05)，N为生成单元数。

In addition, ioding was found to be an efficient catalyst for the imino Diels-Alder reaction of N-arylimine and enol ethers and the reaction provided tertrahydroqinolines in good yields. One pot synthesis of tetrahydroqinolines from aldehyde, aniline and enol ethers was also achieved using iodine as the catalyst. The chemical yield of the"one pot"reaction was comparable with that obtained using preformed N-arylimine.
