Define a function ComputeNegations() that takes an input double vector parameter and an output vector parameter passed by reference. The function stores the negative of each input vector element to the output vector. Ex: If the input is: 3 -2.5 6.0 3.0 then the vector has 3 elements (-2.5, 6.0, 3.0) and the output is: 2.5 -6.0 -3.0 3 #include 4 using namespace std; 5 6 * Your code goes here */ 7 8 int main() { 9 int i; 10 11 12 13 14 15 16 17 18 19 20 vector inputVector; int size; double input; vector negated; cin >> size; for (i = 0; i > input; 1} inputVector.push_back(input);

Matlab Question
For input vector x, write a function to check whether there exists exactly 4 elements in x which are divisible by 3.
1.(a)Write a function named LeastCommonMultiple that takes two integers and returns their smallest common multiple. For instance, least common multiple of 10 and 12 is 60. Create two vectors each having 10 random integers from 2 to 100. Apply the function LeastCommonMultiple to all numbers in your vectors to check their element-wise least common multiples using map2_dbl function in purrr package. For instance, if the random numbers are [2 10 25 13 6 12 11 20 4 8] and [7 6 10 3 12 5 4 30 17 16] then the result should be [14 30 50 39 12 60 44 60 68 16].

Define a function CheckSum() that takes one integer vector parameter and one integer parameter. The function computes the sum of the vector's elements. Then, the function returns true if the sum is not equal to the integer parameter, and returns false otherwise. Ex: If the input is: 4 -69 40 4 then the vector has 4 elements (-6, 9, 4, 0), and the integer parameter is 4. The output is: True, the sum of all the elements is not equal to 4. 1 #include 2 #include 3 using namespace std; 4 5* Your code goes here */ 6 7 int main() { 8 9 10 11 12 13 14 15 16 17 vector inVector; int size; int input; int i; int x; bool result; // Read the vector's size, and then the vector's elements cin >> size; for (i = 0; i < size; ++i) {
You may insert an element into an arbitrary position inside a vector using an iterator. Write a function, insert(vector, position, value) which inserts value into position inside the vector and returns true. If position is out of range, then return false #include <vector>using namespace std; bool insert(vector<int>& v, size_t pos, int value){ ........ }
In the following questions you need to import functions from Numpy. For example the computation of matrix determinants can be done with the help of the function det of the library numpy.linalg. Please list the commands required for the function to work The first photo is 3a. The other photo has the remaining questions.
6) While there is a built-in pop_back() method for vectors, there is no built-in pop_front method. Suppose a program needs a pop_front() method that will remove the first element from the vector. For example if the original vector is [1, 2, 3, 4, 5], then after passing in this vector to pop_front() the new resulting vector will be [2, 3, 4, 5]. Which of the options below is the correct implementation of pop_front()? Group of answer choices D-) void pop_front(vector<int> &v){ for(int i=0; i<(v.size()-1); i++)v[i+1] = v[i]; v.pop_back(); } C-) void pop_front(vector<int> &v){ for(int i=0; i<(v.size()-1); i++)v[i] = v[i+1]; v.pop_back(); } B-) void pop_front(vector<int> &v){ for(int i=0; i<v.size(); i++)v[i+1] = v[i]; v.pop_back(); } A-) void pop_front(vector<int> &v){ for(int i=0; i<v.size(); i++)v[i] = v[i+1]; v.pop_back(); } 7) Suppose a program has the following vector: [99, 23, 55, 71, 87, 64, 35, 42] The goal is to…
Write a function named mean that accepts as a parameter a reference to a vector of real numbers, and returns the arithmetic mean (average) of the integers in the vector as a real number. For example, if the vector passed contains {2.0, 4.5, 6.5, 1.0}, your function should return 3.5. If the vector is empty, return 0.0. Do not modify the vector that is passed in.
Write a function named addStars that accepts as a parameter a reference to a vector of strings, and modifies the vector by placing a "*" element between elements, as well as at the start and end of the vector. For example, if the vector v contains {"the", "quick", "brown", "fox"}, the call of addStars(v); should modify it to store {"*", "the", "*", "quick", "*", "brown", "*", "fox", "*"}.
