Chronological sequence of developments:

Scripting languages gained more popularity with the explosion of World Wide Web (WWW) during 1990’s. Scripting languages are mainly used for developing web pages which are interpreted by the web browsers.

JavaScript appeared in 1994, developed by Netscape replaced the traditional static arrays.

All the character strings and arrays were of having dynamic lengths.

So, array indices are not checked for validity.

In 1995, PHP included the dynamic array properties of arrays from JSP and hashes from Perl.

Hashes are advanced form of array.

In an array, each element can be accessed by the index, but sometimes this becomes extremely difficult as the index itself is not known...

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.
