It's the value of variable rows which was input is greater than 18, line 14 resets the value of variable rows to 18. This limits input ensuring that the value will always be 18 or less. Next comes the binary math. To accomplish the binary math, I added variable a declared up here at line seven. The first step was to have the number of rows. This is accomplished by the bit shift operator here that shifts the bits, right one space. The result is stored in variable a which has half the value of variable rows and its output here at line 19. Line 20 does pretty much the opposite doubling the value using the left shift operator, one bit position which doubles the value stored in variable a, output at line 21. Let's build and run to…
