- 某国为了防御敌国的导弹袭击,发展出一种导弹拦截系统,但是这样的导弹拦截系统有个缺陷,虽然他的第一发炮弹能够达到任意高度,但是以后每一发炮弹都不能高于前一发的高度。某一天,雷达捕捉到敌国的导弹来袭。由于该系统还在使用阶段,所以只有一套系统,因此有可能不能拦截所有的导弹。输入导弹依次飞来的高度(雷达给出高度数据是不大于30000的整数),计算这套系统最多能拦截多少导弹,如果要拦截所有的导弹最少配备多少套这种导弹系统。 三;问题分析: 该系统的第一发炮弹能够达到任意高度,所以要求出系统最多能够

sell
- 输入数据的第一行为两个正整数M(M<=1000),N(N<=30),分别表示王伯的资金和鱼的种类。以下N行,每行有两个正整数S(1<=S<=N),T,分别表示某种鱼的编号以及该鱼的价格。 接着,每行有两个整数P,Q。当P,Q均大于0时,表示P,Q不能共处;当P,Q均等于0时,表示输入的结束。 Output 输出数据的第一行为两个正整数X,Y,分别表示所买鱼的条数和总花费。以下X行,每行有一个正整数,表示所买鱼的编号。编号按升序排列输出。 如果题目有多个解,
