WebIn graph theory and theoretical computer science, the longest path problem is the problem of finding a simple path of maximum length in a given graph.A path is called simple if it does not have any repeated vertices; the length of a path may either be measured by its number of edges, or (in weighted graphs) by the sum of the weights of its edges.In contrast to the … WebOct 1, 2024 · Always check for a new max for each of these 3 use cases by adding the path value of the left subtree and right subtree. m=max(m,l+r). It is OK to add l and r together when checking for a new max for each of the 3 use cases above, since l and/or r are set to 0 when applicable ( i.e. for case 2: 0+0==0 and for case 3: l+0==l XOR 0+r==r).
