Pls solve this question correctly in 5 min i will give u like for sure direct(src, graph) uses Djikstra’s single source shortest path algorithm to find the shortest path from the source to each other node in the network. It is recommended that you use the included heap data structure, as it has a method for decreasing keys when a lower cost path is found. def direct(src, graph): # TODO return {}

Heuristic System

The term heuristic is derived from the Greek word heurisko, which means “I find, discover”. Heuristics can be mental shortcuts or approaches designed from previous experiences. The main aim of the heuristic approach is to find a good enough solution to solve the problem. Test and mistake, rule of thumb, or an educated estimate are all examples of heuristics. These methods are sufficient for achieving an immediate, brief aim. When a heuristic is used in practice, it works as predicted. It can, however, produce systematic errors. Trial and error is an important heuristic that may be used in a variety of situations, from cross-linking nuts and bolts to determining the values of given input variables in mathematical puzzles. Additional hypotheses, visual illustrations, simplification, and forward or backward reasoning are all common heuristics in mathematics.
