It does look like the BFS and DFS approach have the same time complexity and space complexity but if I have got that wrong, how do I know when to use DFS and when to use BFS particularly the grid questions involving number of components?(The editorial suggests any of DFS or BFS so sti...

time complexity: space complexity: 4. BFS frontier is first-in-fist-out queue 5. BFS的性质 complete: BFS是complete的。 optimal: BFS是optimal的,因为找到的第一个解是最shallow的。 time complexity: 和DFS一样是 O(b^m) space complexity: dfs的space complexity是linear的,而bfs是指数的 O(b^m) ...
DFS是优先访问当前节点的子节点,当所有子节点遍历完成后,再返回当前层级访问下一个兄弟节点。树的DFS有很多种,包括pre-order, in-order and post-order,图中选择的是pre-order traverse。 了解3种树的DFS遍历方法请戳:traverse trees time/space complexity - DFS vs BFS ...
We continue this line of work focusing on space. Our first result is a simple data structure that can maintain any subset $S$ of a universe of $n$ elements using $n+o(n)$ bits and support in constant time, apart from the standard insert, delete and membership queries, the operation ...
not far from the root of the tree:BFS, because itisfaster togetcloser node//If the tree is very deep and solutions are rare:BFS, DFS will take a longer time because of the deepth of the tree//If the tree is very wide:DFS,forthe worse cases, both BFS and DFS time complexityisO(N...
