Write a program that prints the U. S. presidential election years from 1792 to present day, knowing that such elections occur every 4 years. Hint: Initialize your loop variable to 1792. Don't forget to use

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.
