- Choose : Find the log of each of the 3 elements in a row vector ? 1-v=[ log2 log5 log6] 2-v=log[2 5 6] 3-v=[2 5 6];>> log(v)There is an array with the original content as follows5,6,7,20,33,44,46,47,48,99,101,102,105Now execute Sequential search, and the state of the sorted array has been completed in the array, how many comparisons are required for the following numbers?48 : ___100 : ___Which of the following data structures store values in contiguous memory? Check all that apply . Vector Linked List Dynamic Array Map Array
- There is an array with the original content as follows12,6,32,45,98,56,85,21,58,69,79,84,86,91Now execute Sequential search, how many comparisons are required for the following numbers?20 : ___45 : ___Integer dataSize is read from input. Then, strings and integers are read and stored into string vector subjectList and integer vector pageList, respectively. Lastly, integer pageThreshold is read from input. Set matchCount with the number of element pairs with a page greater than or equal to pageThreshold. Output the subject of each pair found with a page greater than or equal to pageThreshold. End with a newline. Ex: If the input is: 3 Environment 416 Cooking 353 Science 306 349 Then the output is: Environment Cooking Total: 2 By using the following code: #include #include using namespace std; int main() { int numElements; int pageThreshold; int matchCount; unsigned int i; cin >> numElements; vector subjectList(numElements); vector pageList(numElements); for (i = 0; i < subjectList.size(); ++i) { cin >> subjectList.at(i); cin >> pageList.at(i); } cin >> pageThreshold; /* Your code goes here */ cout << "Total: " << matchCount;…If A is a circular array of MAX elements, and rear is an index into that array, what is the formula for the index after rear? a. (rear % 1) + MAX b. rear + (1 % MAX) c. rear % (1 + MAX) d. (rear + 1) % MAX
- Write a code that can create a [n×m] dimensional matrix. Take the values of all the elementsfrom the user and write a code that can swap all the values of its first row with its last row. After swapping, add all the values of the last column.Using Rstudio, Create a list that contains a numeric vector from (1 to 30, 34, 45, 47, and 50 to 70), a character vector that repeat the elements A, B, and C 30 times, and a 2 x 3 matrix that contains a number from 101 to 106 filled by rows.Modify the existing vector's contents, by erasing the element at index 1 (initially 200), then inserting 100 and 102 in the shown locations. Use Vector ADT's erase() and insert() only, and remember that the first argument of those functions is special, involving an iterator and not just an integer. Sample output of below program with input 33 200 10: #include <iostream>#include <vector>using namespace std; void PrintVectors(vector<int> numsList) {unsigned int i; for (i = 0; i < numsList.size(); ++i) {cout << numsList.at(i) << " ";}cout << endl;} int main() {vector<int> numsList;int userInput;int i; for (i = 0; i < 3; ++i) {cin >> userInput;numsList.push_back(userInput);} /* Your solution goes here */ PrintVectors(numsList); return 0;} Please help me with this problem using c++.
- If a and b are two non-empty numerical row vectors (of different lengths) present in Matlab Workspace, what command would you use to create a new vector, called c, that is a combination of a and b (b elements are appended at the end of a)? c = a + b c = transpose(a,b) c = [a; b] c = [a, b]Need help fixing the second line.
