Program Plan Intro

Finding all permutations for a set

Program Plan:

Include required file.

Define the structure for node.

Declare elements in “vector” type.

Declare variable for next value in “NodeValue” type.

Declare function for display permutations.

Declare function for compute permutations with recursively.

Declare function for display vector elements of set.

Define main function.

Call the function “displayPermutations” with one parameter.

Define function “displayPermutations”.

Create a pointer for node.

Declare the set in “vector” type.

Fill the set with first “n” whole elements.

Call the function “displayVectorElements” to print the vectors.

Then compute the permutation for given set by calling the function “recursivePermutations”.

Performs “while” loop. This loop executes until the pointer is equal to “NULL”.

Display the values in set by calling the function “displayVectorElements”.

Then delete and move to the next value.

Define function “recursivePermutations”.

This function is used to returns a list holding all of the permutations of the given list of elements.

In this function, first assign the pointer list to “NULL”.

Then performs base case if the size of the vector element is “1”. Otherwise performs recursive case.

Compute the permutations for smaller set of elements by recursively call the function “recursivePermutations”.

Define function “displayVectorElements”.

This function is used to display the elements of set.

Algorithm design with sorting. Each of n users spends some time on a social media site. For each i = 1, . . . , n, user i enters the site at time ai and leaves at time bi ≥ ai. You are interested in the question: how many distinct pairs of users are ever on the site at the same time? (Here, the pair (i, j) is the same as the pair (j, i)).Example: Suppose there are 5 users with the following entering and leaving times: Then, the number of distinct pairs of users who are on the site at the same time is five: these pairs are (1, 2), (1, 3), (2, 3), (4, 6), (5, 6). (Drawing the intervals on a number line may make this easier to see).(a) Given input (a1 , b1),(a2 , b2), . . . ,(an, bn) as above in no particular order (i.e., not sorted in any way), describe a straightforward algorithm that takes Θ(n2)-time to compute the number of pairs of users who are ever on the site at the same time, and explain why it takes Θ(n2)-time.
