Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.

Question

Consider the weighted interval scheduling problem, we have the following iterative solution (see 1.2.6 (and earlier
sections if needed) of L6) to the problem:
Assume we have n requests (1. n). For each request i, v(i) is the value of /.
Recall we have defined function previous in class.
*****
Line 1: for i from 0 to n, M[i]:= 0.
Line 2: for i from 1 to n, M[i]:= max(v(i) + M[previous(i)], M[i-1])
SEE Per
a) Write down precisely what is the intended meaning of the data structure M[...]
b) Why do we do line 1?
c) Explain the meaning of M[i]:= max(v(i) + M[previous()], M[i-1]) in Line 2.

Question 2: The game of "FastestPath" consists of a path (a 1-D array) with n positive integers to represent n cities in a path (except the first index which has always value 0). The aim of the game is to move from the source city (located at index 0) to destination (located at last index) in the shortest time. The value at each index shows the travel time to enter the city located in the corresponding index. Here is a sample path where there are 6 cities (n is 6): 0 5 90 7 61 12 Always start the game from the first city and there are two types of moves. You can either move to the adjacent city or jump over the adjacent city to land two cities over. The total travel time of a game is the sum of the travel times of the visited cities. In the path shown above, there are several ways to get to the end. Starting in the first city, our time so far is 0. We could travel to city 2, then travel to city 4, then travel to last city for a total travel time of 90 + 61 + 12 = 163. However, a…
