Common Time Zones Function Name: commonTimeZones() Parameters: code1( str ), code2( str) Returns: list of common time zones ( list ) Description: You and your friend live in different countries, but you figure there's a chance that both of you might be in the same time zone. Thus, you want to find out the list of possible time zones that you and your friend could both be in. Given two country codes, write a function that returns a list of the time zones the two countries have in common. Be sure not to include any duplicate time zones. If the two country codes do not have any common time zones, return the string 'No Common Time Zones' instead. Note: You can assume that the codes will always be valid. example test cases: >>> commonTimeZones('can', 'usa') [UTC-08:00', 'UTC-07:00', 'UTC-06:00', 'UTC-05:00', 'UTC-04:00] >>> commonTimeZones('rus', 'chn') [UTC+08:00] For this assignment, use the REST countries API (https://restcountries.com/#api-endpoints-v2).

Consider the following equation for the sum of a finite arithmetic series: S, = n(a, ta where n is the number of elements in the series, a is the first element of the series, and a, is the last element of the series. Write a method that returns the sum of the elements stored in the array in 8 above. The array must be passed to the method as an argument. Your solution should implement the equation for the sum S.

In Java In designing a building, structural engineers must determine whether each of thebuilding’s support columns is thick enough to support the column’s expected load.Assume the column is wooden and has a solid square cross section. To be safe, allthree of these conditions must be met:• The column should not be too slender, that is:height / width ≤ 50, where 50 is a special value called the slendernesslimit.• To prevent the column from buckling, make sure this requirement ismet:expected load ≤ (0.3*E*area) / (height/width)2,where E = 1,700,000 psi is a special value called the modulus ofelasticity.• To prevent the column from compressing, make sure this requirementis met:expected load ≤ area * stress,where stress = 1450 psi = maximum allowable stress parallel to thegrain.Write a program that determines whether a wooden column with a given height isthick enough to support a given expected load. More specifically, read in height,width, and expected load values and then print, “The…

To write an application that uses recursion to solve a problem. Details: Create a class called Power that computes the value of base exponent. The class should have one recursive method: • public static int power(int base, int exponent) – Which computes the value of base exponent using recursion, returning the result. The recursion step should use the following relationship base exponent = base x base exponent - 1 and the termination condition should occur when exponent is equal to 1, because base 1 = base NOTE: For the power method, assume the exponent parameter value is always greater than 0. Create a second class called PowerTest that contains the main method, and tests the Power.power method. The test class does not need to ask for input from the user of the class, nor does it need to do any additional error checking. Upload both source files to Blackboard. Note: Ensure that your program is properly formatted and it follows all Java naming conventions.
