Answer:
In Python:
N = int(input("Positive integer: "))
if N > 0:
flag = False
for i in range(1,N+1):
if i * i == N:
flag = True
break
print(str(flag))
else:
print("Positive integer only")
Explanation:
N = int(input("Positive integer: "))
If the number is positive
if N > 0:
This initializes a boolean variable to false
flag = False
This iterates from 1 to the input integer
for i in range(1,N+1):
This checks if th number is a square of some integer
if i * i == N:
If yes, flag is set to true
flag = True
The loop is exited
break
This prints either true or false, depending on the result of the loop
print(str(flag))
If otherwise, that the number is not positive
<em>else:</em>
<em> print("Positive integer only")</em>

Answer: Column F
Explanation: In Microsoft excel, for the sake of robustness and to aid the effectiveness of updating formulas across cells. The reference of cells are treated as relative which means that when formulas are copied across columns or within rows, they get updated automatically. However, some numbers may be treated as constants such that we do not want them to change or be updated as we move acisss cells. Thus, such numbers are treated Given absolute references, which is made possible by adding a '$' prefix before the colum alphabet or row number or both. in the scenario given above, the row has the $ prefix, hence, it is absolute and will not change but the column alphabet does not and hence, treated as relative.
