Question

In the process of swapping elements and changing signs, what is the result of the following step?

A) [-4 3 2 -2]
B) [2 -3 -2 4]
C) [2 -2 -3 4]
D) Unable to determine

Answer 1

The result of the step in swapping elements and changing signs is [2 -2 -3 4].

Step-by-step explanation:

In the process of swapping elements and changing signs, the result of the given step can be determined by rearranging the elements and changing their signs accordingly. In this step, we have the initial array A) [-4 3 2 -2] and we need to swap elements and change signs to match the array B) [2 -3 -2 4].

1. Swap the first and second elements, which gives us [-3 2 2 -2].
2. Change the sign of all elements, resulting in [3 -2 -2 2].
3. Swap the third and fourth elements, giving us [3 -2 2 -2].

The final result after swapping elements and changing signs is C) [2 -2 -3 4]. Therefore, the correct option is C.
