Sorting and Monotonicity When a problem does not enforce a specific elemant order, applying a sort operation often introduces monotonicity. This property simplifies constraint checking and enables efficient querying through prefix sums combined with binary search. Processing Cumulative Constraints By sorting the input array and computing its pr ...

Prim's Algorithm for Minimum Spanning Trees Prim's algorithm utilizes a distance array where dist[j] represents the shortest distance from node j to the current connected component. The process begins by selecting an arbitrary starting node and initializing distances to all other nodes. Algorithm Steps: Initialize all distances to infinity exc ...
