makkiz [27]

Answer:

  1. output = ""
  2. for i in range(7):
  3.    if(i % 3 == 0):
  4.        for i in range(5):
  5.            output+= "*"
  6.        output += "\n"
  7.    else:
  8.        for i in range(2):
  9.            output += "* "
  10.        output += "\n"
  11. 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).
