Analyze the following code: class test { public static void main(string[] args) { system. out. println(xmethod((double)5)); } public static int xmethod(int n) { system. out. println("int"); return n; } public static long xmethod(long n) { system. out. println("long"); return n; } }

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.
