push: This operation adds an element to the top of the stack. pop: This operation removes the top element from the stack. peek: This operation allows you to access the top element of the stack without removing it. isEmpty: This operation checks if the stack is empty or not. Stacks are...
For each size of the maximum matching, we do a sequence of DFS-s that in total explore every edge at most once, so the DFS part has complexity O(n+m)O(n+m). We also need to find the edge with the smallest key, that happens O(m)O(m) times. Each push and pop to the ...
