Let the max deadline be m. We create m+1 individual sets. If a job is assigned a time slot of t where t >= 0, then the job is scheduled during [t-1, t]. So a set with value X represents the time slot [X-1, X].

WebDisjoint–set forests are data structures where each set is represented by a tree data in which each node holds a reference to its parent and the representative of each set is the root of that set’s tree. Find follows parent nodes until it reaches the root. Union combines two trees into one by attaching one tree’s root into the root of the ...
