The kind of wire and circuit breaker are:  grounding wire such as fairly large bare copper wire.
<h3>What is the best wire for the above?</h3>
A 20A, 120V small-appliance branch circuit is known to be  used in the case above.
Note that Electric range circuits needs about 50-amp, 240-volt made for circuit that is said to supplies the power to the range or oven via  a 6-3 electrical wire.

Answer:
The sum of all positive even values in arr
Explanation:
We have an array named arr holding int values
Inside the method mystery:
Two variables s1 and s2 are initialized as 0
A for loop is created iterating through the arr array. Inside the loop:
num is set to the ith position of the arr (num will hold the each value in arr)
Then, we have an if statement that checks if num is greater than 0 (if it is positive number) and if num mod 2 is equal to 0 (if it is an even number). If these conditions are satisfied, num will be added to the s1 (cumulative sum). If num is less than 0 (if it is a negative number), num will be added to the s2 (cumulative sum).
When the loop is done, the value of s1 and s2 is printed.
As you can see, s1 holds the sum of positive even values in the arr
