SELECT statement: It is used to retrieve information from the table or database . The syntax for the “SELECT” statement is given below: Syntax: SELECT * FROM table_Name; DISTINCT Keyword: “DISTINCT” keyword is used to avoid redundant data (removing duplicate values) from a column. The syntax for “DISTINCT” keyword is as follows: SELECT DISTINCT column_Name FROM table_Name;

Question

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
