- 5. Write a program Java to search for the key element from the give list and display its location using Binary Search. The list is: 33, 55, 11, 99, 22, 88, 77, 66, 44, and the key is 99.A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Output "None" if name is not found. Ex: If the input is: 3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309 Your program must define and call the following function.

- 4. Let there are N numbers in a list and that list is said to be a UB Jumper if the absolute values of the difference between the successive elements take on all the values 1 through N-1. For example, 2 1 4 6 10 is a UB Jumper because the absolute differences between them are 1 3 2 4 which is all numbers from 1 to (5 - 1) or 4. Write a python program that takes a number sequence as input and prints whether it is a UB Jumper or Not UB Jumper. Input will stop after getting "STOP" as input. (Number order or absolute difference order doesn't follow any sequence.) Sample Input Sample Output 1423 214 6 10 142 -1 6 UB Jumper UB Jumper Not UB Jumper STOPdef hike(lists: list[list[int]], start: tuple[int, int],end: tuple[int, int]) -> int:"""Given an elevation map <lists> and a start and end calculate the cost itwould take to hike from <start> to <end>. If the start and end are the same, then return 0.Some definitions and rules:1. You can only hike to either a vertically or horizontally adjacentlocation (you cannot travel diagonally).2. You must only travel in the direction of the <end_point>. Moreexplicitly, this means that any move you make MUST take you closerto the end point, so you cannot travel in the other direction.3. We define the cost to travel between two adjacent blocks as theabsolute difference in elevation between those blocks.4. You will calculate the naive route here, so at every position, youwill have two choices, to either move closer to the end point alonga row, or along a column, and you will chose the position that coststhe least at that point (you do not need to look ahead to see if…9.Please Implement quicksort in a JAVA programming language.

- Write in Python: A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes in word pairs that consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Assume the search name is always in the list. Ex: If the input is: Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309The 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 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…
