5.03-3. Dijkstra's Algorithm (3, part 3). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E to all other nodes using Dijkstra's algorithm.

The map-reduce framework is quite useful for creating inverted indices on a setof documents. An inverted index stores for each word a list of all documentIDs that it appears in (offsets in the documents are also normally stored, butwe shall ignore them in this question).For example, if the input document IDs and contents are as follows:1: data clean2: data base3: clean basethen the inverted lists woulddata: 1, 2clean: 1, 3base: 2, 3Give pseudocode for map and reduce functions to create inverted indices on agiven set of files (each file is a document).Assume the document IDis availableusing a function context.getDocumentID(), and the map function is invokedonce per line of the document. The output inverted list for each word should bea list of document IDs separated by commas. The document IDs are normallysorted, but for the purpose of this question you do not need to bother to sortthem.
write a C++ program to Given a matrix of dimension m*n where each cell in the matrix can have values 0, 1 or 2 whichhas the following meaning:0: Empty cell1: Cells have fresh oranges2: Cells have rotten orangesSo we have to determine what is the minimum time required so that all the oranges becomerotten. A rotten orange at index [i,j] can rot other fresh orange at indexes [i-1,j], [i+1,j], [i,j-1],[i,j+1] (up, down, left and right). If it is impossible to rot every orange then simply return -1.Examples:Input: arr[][C] = { {2, 1, 0, 2, 1},{1, 0, 1, 2, 1},{1, 0, 0, 2, 1}};Output:All oranges can become rotten in 2 time frames.Input: arr[][C] = { {2, 1, 0, 2, 1},Tahir Iqbal Department of Computer Sciences.

please provide orignal solution.3. Big-O Dating Game. Match each data structure with the correct desired behavior so that each algorithm achieves its best Big-O (runtime efficiency). Feel free to justify each match. Structure A: I'm the kind of algorithm who wants a data structure that isn't slow minded. When I ask it a question, I expect my data structure to be able to find the answer quickly and efficiently, but I don’t need to keep my data in any particular order. (What data structure would be appropriate in a find-heavy algorithm?) Structure B (2): I like to keep things tidy. I like it best when everything is in its rightful place and would like to meet a data structure that isn't going to make that difficult. (What data structure would be appropriate for an algorithm that needs to maintain the ordering of my data?)
Consider a situation of a boarding gate of a plane where passengers are allowed to board on the place based on their age. All passengers are on a line (queue) to board on the place, however, the oldest one is always allowed to board first no matter when he/she got in the line (queue). In this case, you cannot sort the passengers by their age, however, you know that oldest ones are always at the top of the line. This is an example of a priority queue where data will be accessed and processed based on their level of priority. Suppose you need to organize such type of data so that the data in highest priority can be accessed in a constant time, O(1). What type of data structure would you use in such cases? Justify your answer.
