Implement a static generic method named problem3_reverse that takes as a parameter a generic list, reverses it and returns it. Note: the method must modify the original list.

Q3.There are special semaphores called counting semaphores. What kinds of things are they used for?

Show me a nice UI. Distinguish between GUIs, NUIs, and CLIs.

Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used…
