## [Solved] : Question 100069

Invent your own function that does some useful computation of your choosing. Do not copy the
function from somewhere else. Use incremental development, and record each stage of the
development process as you go. Finally, print output that demonstrates that the function works as
you intended.
Include all of the following in your Learning Journal:
An explanation of each stage of development, including code and any test input and output.
The output of three calls to your function with diàerent arguments.

## [Solved] : Question 100129

3.Create a class node that contains a random value -50<x<50, Create a 2-d array (size m, n entered by the user ) of these random nodes find the internal square with the largest sum of values within it. For example if the user enters m = 4, and n=3 and values are generated it might look like this

-324-168
-2 5-2211
5-10312
335-17-33

You might think the maximum sub-matrix would be
-25
5-20
335 sum =26

But it is actually
8
11
12 sum =31 you need to check all possible rectangles, this is a 2d version of
the greatest common substring problem.

Compute the acceleration of gravity for a given distance from the earth’s center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth’s center (stored in variable distCenter).

Do Exercise 6.4 from your textbook using recursion and the is_divisible function from Section 6.4. Your program may assume that both arguments to is_power are positive integers. Note that the only positive integer that is a power of “1” is “1” itself.

After writing your is_power function, include the following test cases in your script to exercise the function and print the results:

print(“is_power(10, 2) returns: “, is_power(10, 2))
print(“is_power(27, 3) returns: “, is_power(27, 3))
print(“is_power(1, 1) returns: “, is_power(1, 1))
print(“is_power(10, 1) returns: “, is_power(10, 1))
print(“is_power(3, 3) returns: “, is_power(3, 3)
