For each of the following problems, you should write your answer as an expression. Do notgive the final numeric value. For example, if your answer is the number of6-permutations of a set with 10 elements, you should write P(10,6) or 10!/4! or 10 × 9 × 8 ×7 × 6 × 5, but not 151200. (20 pt., 5 pt. each) How many different bit strings of length 9...5.1 ...contain at least three O's?5.2 ...start and end with the same digit and contain at most two 1's?5.3 ...start with a 1 or contain exactly four 0's?5.4 ...contain at least four consecutive 1's?

Implement a mergeUniqueValues(arr1, arr2) method. When passed two arrays of strings, it will return an array containing the strings that appear in either or both arrays in sorted order. And the returned array should have no duplicates. For example, if you have two string arrays: arr1: {“Bear”, “Elephant”,”Fox”}arr2: {“Panda”, “Elephant”,”Eagle”} Calling mergeUniqueValues(arr1, arr2) should return a merged and sorted array like: Bear, Eagle, Elephant, Fox, Panda
Please show me how to remove an element from a given set in Python, declare a set of your choice with atleast 10 elements. Then display the original set and the set after removal of each element. Remove any three elements from the set.
Write a Java application CountryList. In the main method, do the following:1. Create an array list of Strings called countries.2. Add "Canada", "India", "Mexico", "Peru" in that order.3. Use the enhanced for loop to print all countries in the array list, one per line.4. Add "Spain" at index 15. Replace the element at index 2 with "Vietnam". You must use the set method.6. Replace the next to the last element with "Brazil". You must use the set method. You willlose one point if you use 3 in the set method. Do this in a manner that would replace thenext to the last element, no matter the size of the array list.7. Remove the object "Canada" Do not remove at an index. Your code should work if"Canada" was at a different location. There is a version of remove method that willremove a specific object.8. Get and print the first element followed by "***"9. Call method toString() on countries to print all elements on one line.10. Use the enhanced for loop to print all countries in the array list,…
in Python Minima in permutations. Write a program that takes an integer n from the command line, generates a random permutation, prints the permutation, and prints the number of left-to-right minima in the permutation (the number of times an element is the smallest seen so far). Then write a program that takes integers m and n from the command line, generates m random permutations of length n, and prints the average number of left-to-right minima in the permutations generated
a multiset is a collection of objects, just like a set, but can contain an object more than once ( the order of the elements still doesn't matter). for example, {1,1,2,5,5,7} is a multistset of size 6. a. how many sets of size 5 can be made using the 10 numeric digits 0 through 9? b. how many multisets of size 5 can be made using he 10 numeric digits 0 through 9?
6. In Java Write a static method transpose() that receives as parameter, a 2D square array numArof integers, and swaps the row and column of each element. For example:6 7 8 0 6 3 1 23 2 4 5 → 7 2 5 01 5 8 2 8 4 8 92 0 9 3 0 5 2 3Hint: Once you find the largest-sum column, you will need to swap its entries with the first column,element-by-element.
How do you compute the union, intersection, and difference of two sets, using just the methods of the Set interface and without using loops? (Java)
*************************PLEASE READ This paragrah first************* How would I go about using a set for the question below. The current code that I have that works, is at the bottom. Unfortuantely, it is too slow and gets rejected by the tester. The explanation of the problem suggests using sets "To allow your function to execute in a sure and speedy fashion even for millions of elements, you should use a set to keep track of which elements are already part of the prefix of the sequence generated so far." I need my code to work in less than 15 seconds. I have already asked this question and was given somthing very close to what I already had and it didn't contain any sets. My code works, it is just too slow. If you cannot help please reject the question so I don't lose another question on this one. Thank you in advance for spending your time to help me. ********************************************************************* Recamán's sequence def recaman_item(n):Compute and return…
Let A={1,2,3...,10}. How many subsets B of A where B = │4│and the smallest element in B is 4? Write a computer program in java or develop an algorithm that lists all subsets according to the part (a). (Please display the all subsets).
(6) Write out the POWER SET. Keep in mind a subset can be made of any combination of elements appearing in the original set (provided it’s a UNIQUE combination).{2,4,8}
Use the right loop for the right assignment, using all the follow- ing loops: for, while without hasNext(), while with hasNext() and do-while. So I cannot use array. it has to be done in java.
Transcribed Image Text Let N be the set of all ounting numbers: 1, 2, 3,.... Consider these set definitions: A = {z € N| (4 < =) A (z < 5)} and B- {{4, 5}} Is the equality A = B true? O Yes, it is true. O No, it is not true. o We need more information in order to decide. Not counting N, are we dealing with two sets or one set in this problem? o One set. O Two sets.
