For any element in keysList with a value greater than 100, print the corresponding value in itemsList, followed by a space. Ex: If keysList = {42, 105, 101, 100} and itemsList = {10, 20, 30, 40}, print:20 30 Since keysList.at(1) and keysList.at(2) have values greater than 100, the value of itemsList.at(1) and itemsList.at(2) are printed. #include <iostream>#include <vector>using namespace std; int main() { const int SIZE_LIST = 4; vector<int> keysList(SIZE_LIST); vector<int> itemsList(SIZE_LIST); unsigned int i; for (i = 0; i < keysList.size(); ++i) { cin >> keysList.at(i); } for (i = 0; i < itemsList.size(); ++i) { cin >> itemsList.at(i); } /* Your solution goes here */ cout << endl; return 0;}

The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…
Jessie has a lot of cooking with her (N). He often remembered the first few letters of the recipe and forgot the others. Like all great chefs, Jessie re-calculated the recipes according to the priority. So, looking at the list of recipes and priorities answers Jessie's questions. Response from Jessie: Giving the first few letters of the recipe; you have to print the perfect recipe in the most important way. Note: Every recipe has a unique value. Please answer this in C++ Only Input 1 flour-with-eggs 100 1 G Output 0
Create an iterator that returns numbers, starting with 1, and each sequence will increase by one (returning 1,2,3,4,5 etc.):
def fquartic(x): return (x**4-1) Find the roots There are two real roots of this function. Even though you may immediately see what those roots are, use scipy.optimize.root_scalar to find those roots one by one: Use the default method (i.e. don't specify a specific method for root finding) Specify appropriate x0 and x1 values for each one of the roots (don't pick them right on top of the roots, but pick them close) Make sure that the converged attribute of your solutions are both True.
JAVA Using the code provided below called intSet create an iterator called sortedElements and the inner class. This will return an interator that will produce each element of the inset in ascending order. Specify and implement an iterator method called sortedElements for IntSet. The iterator method sortedElements returns an iterator that will produce each element of the intset in ascending order. The intset cannot be mutated when the iterator is in use.     Be sure to specify the iterator method before implementation. Do not forget to give the rep invariant and abstraction function for your implementation. Note: IntSet.java has been provided. You can directly add in the code the specification, the implementation of the iterator method sortedElements, and the inner iterator class.     There is a segment of simple testing code for sortedElements in main() close to the end in the provided IntSet.java. The program will not compile until you have properly implemented sortedElements…

TaskGiven an integer, , and space-separated integers as input, create a tuple, , of those integers. Then compute and print the result of . Note: hash() is one of the functions in the __builtins__ module, so it need not be imported. Input Format The first line contains an integer, , denoting the number of elements in the tuple.The second line contains space-separated integers describing the elements in tuple . Output Format Print the result of hash(t). Sample Input 0 21 2 Sample Output 0 3713081631934410656
Chiralitydef is_left_handed(pips): Even though this has no effect on fairness, pips from one to six are not painted on dice any which way, but so that the pips on the opposite faces always add up to seven. (This convention makes it easier to tell when someone tries to use gaffed dice that leave out some spot values.) In each corner of the cube, one value from each pair of opposites 1-6, 2-5 and 3-4 meets two values from the other two pairs of opposites. The math works out correctly in for the 23 = 8 corners of the cube. This still leaves two possibilities how to paint these pips. Look at the corner shared by the faces 1, 2, and 3, and read these numbers clockwise around that corner starting from 1. If these three numbers read out as 1-2-3, that die is left-handed, and if they read out as 1-3-2, that die is right-handed. Analogous to a pair of shoes made separately for the left and right foot, left- and right-handed dice are in one sense identical, yet no matter how you twist and turn,…
