C++ Given code is  #pragma once#include <iostream>#include "ourvector.h"using namespace std; ourvector<int> intersect(ourvector<int> &v1, ourvector<int> &v2) {    // TO DO: write this function    return {};}

Jupyter Notebook Fixed Income - Certicificate of Deposit (CD) - Compound Interest Schedule An interest-at-maturity CD earns interest at a compounding frequency, and pays principal plus all earned interest at maturity. Write a function, called CompoundInterestSchedule, that creates and returns a pandas DataFrame, where each row has: time (in years, an integer starting at 1), starting balance, interest earned, and ending balance, for an investment earning compoundedinterest. Use a for(or while) loop to create this table. The equation for theith year's ending balance is given by: Ei =Bi (1+r/f)f where: Ei is year i's ending balance Bi is year i's beginning balance (note: B1 is the amount of the initial investment (principal) r is the annual rate of interest (in decimal, e.g., 5% is .05) f is the number of times the interest rate compounds (times per year)   The interest earned for a given year is Ei - Bi   Note the term of the investment (in years) is not in the above equation; it is used…

t. Given a string as a parameter to the function, return a square grid filled with all the characters of the string from left to right. Fill empty spaces in the grid with '_'. Sample Input:  stringtogrid Output: {{s, t, r, i}, {n, g, t, o}, {g, r, i, d}, {_, _, _, _}} Complete the function: vector<vector<int> formGrid(string s){}
