How fast (big O notation is enough) can you check if two lists
of n integers each has at least one integer in common? (hint:
sorting a list of n integers – meaning putting them in order, takes
time with the best algorithms we have).

When we have two sorted lists of numbers in non-descending order, and we need to merge them into one sorted list, we can simply compare the first two elements of the lists, extract the smaller one and attach it to the end of the new list, and repeat until one of the two original lists become empty, then we attach the remaining numbers to the end of the new list and it's done. This takes linear time. Now, try to...

C++. Please leave comments explaining. Thank you! Given two unsorted STL lists X and P , write a valid C++ function intersection( X , P ) that returns a new list that contains the elements common to both X and P . For example, if X = 5, 2, 1, 4 and P = 4, 5, 7; your algorithm should return a new list containing 5 and 4 (order is not important). Also specify the running time of your algorithm...

9. (5 points) Please describe an algorithm that takes as input a list of n integers and finds the number of negative integers in the list. 10. (5 points) Please devise an algorithm that finds all modes. (Recall that a list of integers is nondecreasing if each term of the list is at least as large as the preceding term.) 11. (5 points) Please find the least integer n such that f() is 0(3") for each of these functions f()...

Need help with program. I'm stuck
Objectives: In this assignment, we will
practice manipulating lists of data and arranging items in an
ascending/descending order. you will also explore storing
lists/arrays using different sorting algorithms including, the
selection sort, bubble sort, and insertion sort algorithm.
Comparison between the three algorithms are made based on the
number of comparisons and item assignments (basic operations) each
algorithms executes.
Background: Ordering the elements of a list is
a problem that occurs in many computer...

[Code in C] Help me with this. Not sure what to do.
1 Couting Sort You may have learned some sorting algorithms - such as bubble sort ad quicksort in CS 110 and CS 210. This homework is about counting sort. Let n be the number of elements to be sorted. Bubble sort and quicksort assume tha time, which one is larger and which one is smaller. They make no assumption on the values of the elements t we can...

in JAVA program.Use top-down design to design and implement a program to ask the user to enter a list of integers, and then display to the user the mean and median of this list. You should first prompt the user to specify the length of the list of integers. For this assignment, your code should create an array of size 10, and then allow the user to specify the number of integers in their list, up to a maximum of...

Written in Java Your job is to produce a program that sorts a list of numbers in ascending order. Your program will need to read-in, from a file, a list of integers – at which point you should allow the user an option to choose to sort the numbers in ascending order via one of the three Sorting algorithms that we have explored. Your program should use the concept of Polymorphism to provide this sorting feature. As output, you will...
