Kahn’s algorithm for Topological Sorting

Web(a)When using DFS(depth first search) to check for a cycle in a directed, can we simply check for the algorithm visiting a marked node? Explain yes or no. (b) In the DFS based topological sort, what would happen if nodes were pushed on the stack before their children were explored, rather than after? would the algorithm still work? Explain. WebNov 9, 2024 · It's not easy to turn an iterative implementation of DFS into Topological sort, since the change that needs to be done is more natural with a recursive implementation. ... My idea is based on two key observations: Don't pop the next item from stack, keep it to emulate stack unwinding. Instead of pushing all children to stack, just push one. can starlink be used in an rv https://carlsonhamer.com
