Let's go through a case study of data science to understand what is it about. Black Americans Are Much More Likely to Face Tax Audits, Study Finds (Published 2023)A new report documents systemic discrimination in how the I.R.S. selects taxpayers to be audited, with implications for a debate on the agency’s funding.www.nytimes.comNew York times reported said that the IRS seems to be exhibiting s..

A topological sort of a directed, acyclic graph produces a list of graph's vertices such that for every edge from a vertex X to a vertex Y, X comes before Y in the list. There can be more than one valid topoligcal sort. Again, the graph must be acyclic and riected in order to apply topological sorting. The time complexity and space complexity of topological sorting is O(|V| + |E|).

The Bellman-Ford shortest path algorithm, created by Richard Bellman and Lester Ford, Jr,. determines the shortest path from a start vertex to each vertex in a graph. For each vertex, the Bellman-Ford algorithm determines the vertex's distance and predecessor pointer. A vertex's distance is the shortest path distance from the start vertex. A vertex's predecessor pointer points to the previous ve..

Finding the shortest path between vertices in a graph has many applications. Dijkstra's shortest path algorithm, created by Edsger Dijkstra, determines the shortest path from a start vertex to each vertex in a graph. For each vertex, Dijkstra's algorithm determines the vertex's distance and predecessor pointer.A vertex's distance is the shortest path distance from the start vertex. A vertex's pr..
