问题描述 序列Z=<B,C,D,B>是序列X=<A,B,C,B,D,A,B>的子序列,相应的递增下标序列为<2,3,5,7>。 一般地,给定一个序列X=<x1,x2,…,xm>,则另一个序列Z=<z1,z2,…,zk>是X的子序列,是指存在一个严格递增的下标序列〈i1,i2,…,ik〉使得对于所有j=1,2,…,k使Z中第j个元素zj与X中第ij个元素相同。 给定2个序列X和Y,当另一序列Z既是X的子序列又是Y的子序列时,称Z是序列X和Y的公共子序列。 你的任务是:给定2个序列X、Y,求X和Y的最长公共子序列Z。

LiteSQL is a C++ library that integrates C++ objects tightly to relational database and thus provides an object persistence layer. LiteSQL supports SQLite3, PostgreSQL and MySQL as backends. LiteSQL creates tables, indexes and sequences to database and upgrades schema when needed.

This paper studies the problem of tracking a ballistic object in the reentry phase by processing radar measurements. A suitable (highly nonlinear) model of target motion is developed and the theoretical Cramer—Rao lower bounds (CRLB) of estimation error are derived. The estimation performance (error mean and
