Answer:
- output = ""
- for i in range(7):
- if(i % 3 == 0):
- for i in range(5):
- output+= "*"
- output += "\n"
- else:
- for i in range(2):
- output += "* "
- output += "\n"
-
- print(output)
Explanation:
The solution code is written in Python 3.
Firstly, create a output variable that holds an empty string (Line 1).
Create an outer loop that will loop over 7 times to print seven rows of stars (Line 2). In row 0, 3 and 6 (which are divisible by 3) will accumulate up to 5 stars using an inner loop (Line 4-5) whereas the rest of the row will only print two stars with each start followed by a single space (Line 8-9) using another inner loop.
At last, print the output (Line 12).
Real-Time Operating System –
These types of OSs serves the real-time systems. The time interval required to process and respond to inputs is very small. This time interval is called response time.
Real-time systems are used when there are time requirements are very strict like missile systems, air traffic control systems, robots etc.
