Depth First Search

Depth-first search (DFS) also known as Depth First traversal is an algorithm used to traverse or search the nodes in a tree or graph data structure. Traversal usually means visiting all the nodes of a graph. DFS performs in a depth-ward manner. It uses a stack to remember the vertices it has visited. The search starts from the root node, where any arbitrary node is selected as a root node in a graph, and then each node is explored along each branch before performing backtracking. The DFS algorithm uses a recursive technique by following the idea of backtracking. DFS algorithm does this by performing an in-depth search of all the nodes by traversing in a forward direction. If the required node is not found, it starts backtracking to previously visited nodes.

Implement a list of employees using a dynamic array of strings.Your solution should include functions for printing list, inserting and removingemployees, and sorting lists (use Bubble sort in C++ language).Keep list of employees sorted within the list after insertion.See the following example:How many employees do you expect to have?5 (Carriage Return)Menu :1 .

Consider the list x=[10, 20, 45, 68, 90, 100.35]. Write a simple code that computes the average of the numbers in this list. If I asked you to tell me what the maximum number in the list is, what would you do mentally. Think about how you determine the maximum value in the list. with simple python code
The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
The function swap_list_ends in python takes one parameter, L, which is a list. The function then swaps the first and last items in L and returns the object None. Notice that since L is mutable, the changes the function makes to L are visible back in the calling program. SPECIAL CASE: If the list 'L' is empty, then the function does nothing to L and returns None. For example: Test Result L = [1, 3, 9, 2] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [2, 3, 9, 1] L = ['super', 'awesome', 'excellent'] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) ['excellent', 'awesome', 'super'] L = [True, False] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [False, True]
Create a program that removes duplicate integer values from a list. For example if a list has these valuesList = [5, 7, 8, 10, 8, 5, 12, 15, 12]. After applying the removal function, you should have List = [5, 7, 8,10, 12, 15]. In your case you will get the numbers of list from the user.

The function interleave_lists in python takes two parameters, L1 and L2, both lists. Notice that the lists may have different lengths. The function accumulates a new list by appending alternating items from L1 and L2 until one list has been exhausted. The remaining items from the other list are then appended to the end of the new list, and the new list is returned. For example, if L1 = ["hop", "skip", "jump", "rest"] and L2 = ["up", "down"], then the function would return the list: ["hop", "up", "skip", "down", "jump", "rest"]. HINT: Python has a built-in function min() which is helpful here. Initialize accumulator variable newlist to be an empty list Set min_length = min(len(L1), len(L2)), the smaller of the two list lengths Use a for loop to iterate k over range(min_length) to do the first part of this function's work. On each iteration, append to newlist the item from index k in L1, and then append the item from index k in L2 (two appends on each iteration). AFTER the loop…
do these coe in python: Suppose you have the following animal names in a list: cat, dog,mouse, hamster. Write a code that prints the first letter, the last letter, andthe length of each animal’s name. Print out all the animal names that havea length greater than 3. after that Write a program that counts the number of aletter that appears in the list (i.e. the frequency of the letter).
Write a function findMaxTuple() that gets a list of tuples as a parameter, finds and returns the tuple with maximum sum inside the list. Write Python statements that create a sample list that has tuples inside (you can use the list of tuples in the sample run below), then use findMaxTuple() function to get the tuple with maximum sum and print it.
Write a python function that takes a list of numbers(integer) and a number(integer) as arguments. Your task is to identify pairs of numbers from the list whose ABSOLUTE difference is equal to the 2nd argument(number). If such a pair of numbers don’t exist in the list, then print ‘Not Possible’. Otherwise, print those pairs in a list format INSIDE the function. Note: You need to use the built-in function abs(number1, number2) to get the difference between two numbers. ================================================ Function Call1: function_name([1, 17, 22, 38, 5, 11], 5) Sample Output1: [[17, 22]] Explanation1: The difference between 17 and 22 is 5. 17- 22 = 5(absolute value). So, the output pair is [17, 22]. Since there are no other pairs, only [17, 22] is printed in the answer list.
