- Write a function that accepts a number, N, and a vector of numbers, V. The function will return two vectors which will make up any pairs of numbers in the vector that add together to be N. Do this with nested loops so the the inner loop will search the vector for the number N-V(n) == V(m). n and m are indices in the vector of numbers. Example A = [1,2,3,4,5,6, 7] Google(5, A) Return [1,2,3,4] and [4,3,2,1] being the pairs that sum to 5. Notice that each pair appears twice. Try to write code that does not do this.Write a C++ program that does the following steps: stores 16 integer random numbers in a vector container V. The random numbers range in value (0 – 199). One can generate such numbers by invoking the random number generation function, rand( ) and using the % (mod)operator Prior to using the rand( ) function, initialize the random number generator with the srand(17) Print the entire vector after filling the vector container V Create a function Total(vector iterator, Size) that returns the total sum of the vector V Count the number of values exceeding 85 and print the result Remove all numbers from the vector V that are divisible by 3 Print the entire modified reduced vector after the removal step Create a set S(descending order) from the modified vector V Print Set S Remove the first number in S that is divisible by 4 Print modified Set S6) 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…
- Given two arrays A and B of equal size N, the task is to find a vector containing only those elements which belong to exactly one array - either A or B - but not both. That is, if some element x appears in both A and B it should not be included in the output vector. Complete the implementation of "getVector(vector<ll>A, vector<ll>B, int N)" function. Example: Input: 1 3 5 7 1 3 2 4 6 7 8 Output: 3 5 1 3 2 4 6 8 The driver codes are attached in the images below. DO NOT CHANGE THE PROVIDED DRIVER CODES AT ALL, LEAVE THEM EXACTLY THE SAME. ONLY ADD CODE TO THE "getVector(vector<ll>A, vector<ll>B, int N)" FUNCTIONWrite a function called genericSort() that takes in a numeric or integer vector, sorts it, and returns the indices of the sorted values. It should also print an error if the input is a character. For example, genericSort(c(1,3,7,5)) should return the vector (1,2,4,3). Programming in RIn PYTHON Define a vector of integers with 5 elements Write the following function Given a vector and two indexes, returns a vector where the values at the provided indexes are swapped Example Input: my_vector = [40,51,62,73,84,95] Invokefunction:swap(my_vector,2,4) Output:[40,51,84,73,62,95]
- Write a C++ program define a vector object and initialize it with 3 values and then define an iterator that points to elements of this object, then ask the user to enter 3 more values and then add them to the previous vector and then print all elements in the vector.What would be a way in implementing the Josephus problem in C++ using a vector or a list? That takes in three parameters, one the number of knights for the knight parameter. The second parameter, "skip", is the number of knights to skip and to execute the next night. Then the third parameter "start", is the index of the knight to execute first.Create a function append(v, a, n) that adds to the end of vector v a copy of all the elements of array a. For example, if v contains 1,2, 3, and a contains 4, 5, 6, then v will end up containing 1, 2, 3, 4, 5,6. The argument n is the size of the array. The argument v is a vector ofintegers and a is an array of integers. Write a test driver.
