Question: Let G = ( V , E ) be a directed graph, with positive edge weights. You are also given a vertex w . Design

Let G=(V,E) be a directed graph, with positive edge weights. You are also given a vertex w. Design an algorithm that outputs the set of vertices satisfying:d(x,w)>=2023.d(w,x). Here, d(y,z) is the distance from vertex y to vertex z (this is the length of the shortest path from y to z)
