Suppose we have a graph such as:
If you wanted a path from 0 to 5, in what order will we visit the nodes if we perform DFS and BFS on this graph (assume the lowest element is always pushed...

The time complexity to go over each adjacent edge of a vertex is, say, O(N), where N is number of adjacent edges. So, for V numbers of vertices the time complexity becomes O(V*N) = O(E), where E is...

I need a reasonably smart algorithm to come up with "nice" grid lines for a graph (chart).
For example, assume a bar chart with values of 10, 30, 72 and 60. You know:
