Explanation of Solution

Avoiding the side effect:

It could be changed to remove side effects by having it return the new array state rather than changing the existing array.

The modified method is given below:

//definition of "doubleAll" method

You are tasked with developing a portable system that can be worn to collect health and fitness data. The challenge is to integrate all functions into the smaller form of an ear clip. The device should include heart rate, movement and temperature sensor and wireless communication with a mobile app. Draw a diagram- hardware architecture of the system- including the selection of suitable sensors, communication modules, and an energy-efficient microcontroller. (visualize the components and their connections)
Draw out an example of 3 systems using Lamport’s logical clock and explain the steps in words.
