例句與造句

1. Further consider a function \ mathrm { shortestPath } ( i, j, k ) that returns the shortest possible path from i to j using vertices only from the set \ { 1, 2, \ ldots, k \ } as intermediate points along the way.
2. We know that the best path from i to j that only uses vertices 1 through k is defined by \ mathrm { shortestPath } ( i, j, k ), and it is clear that if there were a better path from i to k + 1 to j, then the length of this path would be the concatenation of the shortest path from i to k + 1 ( using vertices in \ { 1, \ ldots, k \ } ) and the shortest path from \ { k + 1 \ } to j ( also using vertices in \ { 1, \ ldots, k \ } ).
3. It's difficult to find shortestpath in a sentence. 用shortestpath造句挺難的
