I need a program done in java to calculate Lagrange polynomial and all the divided differences needed for the Lagrange polynomial interpolating

Write programs to find the sum of elements of an array of n numbers in both Python and Java. Which of the two programs has higher degree of readability and why?

Solve the following problem with Python IDLE. The goal is to generate digital number signs. For simplicity, you will use only the numerals 0, 1, and 2, and the signs will be vertical. You will develop a collection of functions that can be used to draw numerals in the format commonly used to digital clocks and other displays. You will build the functions in a systematic way, writing a series of steps that build on one another, so it's important to progress through this assignment in order. Use the indicated function names.  # function: horizontal_line# input: a width value (integer)# processing: prints a single horizontal line of the desired size# output: does not return anything# function: vertical_line# input: a shift value and a height value (both integers)# processing: generates a single vertical line of the desired height. the line # is offset from the left side of the screen using the shift value# output: does not return anything# function: two_vertical_lines# input: a width value…

In java how can I define the random integer and random character functions in a separate class in a separate source code file and call these functions from the shape maker
