624 - CD 题意:一段n分钟的路程,磁带里有m首歌,每首歌有一个时间,求最多能听多少分钟的歌,并求出是拿几首歌. 思路:如果是求时常,直接用01背包即可,但设计到打印路径这里就用一个二维数组标记一下即可. const int N=1e3+10; int n,m,a[N],d[N],v[N][N]; int main() { while(~scanf("%d%d",&n,&m)) { memset(v,0,sizeof(v)); memset(d,0,sizeof(…
链接:传送门 题意:有 n 个城市,从城市 i 到城市 j 需要话费 Aij ,当穿越城市 i 的时候还需要话费额外的 Bi ( 起点终点两个城市不算穿越 ),给出 n × n 大小的城市关系图,-1 代表两个城市无法连通,询问若干次,求出每次询问的两个城市间的最少花费以及打印出路线图 思路:经典最短路打印路径问题,直接使用一个二维数组 path[i][j] 记录由点 i 到点 j 最短路的最后后继点,这道题关键是当松弛操作相等时,i 到 j 的最短距离是可以由 k 进行跳转的,这时候需要判断这…
