Programming & Computer Science Answers

A smartwatch is a very useful device developed by several companies these days including Apple, Samsung, Motorola and several others. It has a touch screen interface providing features like GPS tracking, heart rate and sleep monitoring etc. with power efficient batteries. The ARM Cortex processors are used in smartwatches providing several benefits.

Suppose we have to choose between ARM Cortex-A or Cortex-M series architecture for our next generation smartwatch. Which one would you select between the two and why? Support your selection of either architecture with solid reasoning considering memory management, cost, performance and chip size

Write a function in this file called nine_lines that uses the function three_lines (provided below) to print a total of nine lines.

Now add a function named clear_screen that uses a combination of the functions nine_lines, three_lines, and new_line (provided below) to print a total of twenty-five lines. The last line of your program should call first nine_lines and then the clear_screen function.

The function three_lines and new_line are defined below so that you can see nested function calls. Also, to make counting “blank” lines visually easier, the print command inside new_line will print a dot at the beginning of the line:

def new_line():

print('.')

def three_lines():

new_line()

new_line()

new_line()

Draw a flow chart to compute the sum of the series: 

𝑓(𝑥) = 1 + 𝑥 + 𝑥

2 + 𝑥

3 + … + 𝑥

𝑛

Provide a Pseudocode to illustrate the assignment of 10 to X if X < Y otherwise 

5 is assigned to X.
