Answer:
signal repeaters.
Explanation:
The best device to use in this scenario would be signal repeaters. These basically grab an already existing signal and repeats it in a specific direction therefore amplifying the range. These devices are usually used when a large network system is not reaching certain devices that are located too far away. These devices are then placed in midpoints between the network and the device and aimed towards the direction of the device. It then picks up the existing signal and retransmits it to the devices' location so that the device can pick up the network signal and access it.

Answer:
Decision making structures require that the programmer specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.
You'll need a helper variable for this, so depending on your programming language, the solution becomes:
int helper;
helper = arr[i];
arr[i] = arr[j];
arr[j] = helper;
