Answer:
The "A" option is correct.
Explanation:
For CSS flexbox layout, the property "align-content" requires that the space in the flexbox is more than enough to show the items. In this case, to distribute evenly the items and show the first and last items aligned with the start and end of the main axis, the only suitable option is "space-between". This option leaves no space at the start or at the end of the flexbox, distributing the remaining space between the elements into the flexbox.
Answer:
Stack.
Explanation:
Topological sort requires a bit of addition to DFS algorithm.So DFS can be done by two ways that are either you can use recursion or you can use Stack data structure to implement DFS.
Since recursion uses stack memory when it makes recursive calls and if you want to do it iteratively you can stack data structure.
