Only 20 will do

Many programmers are just crazy about brainteasers: Rubik's cubes, "use two matchsticks to get 100", the Tower of Hanoi, and others. Their brains are wired like that. Let's practice solving some brainteasers in programs. In this case, arrange the plus and minus signs so that the variable result is equal to 20.

Do I need to start a variable declaration with “public static…” when I am declaring it outside the main method? What is the difference?

After executing the program and getting the required output also, why is it showing the status of the task as "In Progress" ? Appreciate inputs on this. Thanks in advance!

you know that the final result must be 20. The last number to be added is d, which is 27. This means, that you somehow have to make the sum of a, b and c equal to something that will take 27 DOWN to 20.

it wasn't but i think the point is to figure it out a little on your own to make your brain think.
