WebStack size in C++ is a property of the compiling/running environment, so it depends on the judge setup. In most judges it is set to a very high value (Codeforces has 256MB), so it's very hard to cause stack overflow. ... dfs(int node, vector &visit, vector &tim, vector &bridge, .. 2 more arguments) WebMar 19, 2024 · To implement the DFS we use stack and array data structure. There are two cases in the algorithm: Whenever we visit a vertex we mark it visited and push its adjacent non-visited vertices into the stack and pop the current vertex from the stack. If all the adjacent vertices are visited then only pop the current vertex from the stack.
