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:
def typeHistogram(it,n):
d = dict()
for i in it:
n -=1
if n>=0:
if str(type(i).__name__) not in d.keys():
d.setdefault(type(i).__name__,1)
else:
d[str(type(i).__name__)] += 1
else:
break
return list(d.items())
it = iter([1,2,'a','b','c',4,5])
print(typeHistogram(it,7))
Explanation:
- Create a typeHistogram function that has 2 parameters namely "it" and "n" where "it" is an iterator used to represent a sequence of values of different types while "n" is the total number of elements in the sequence.
- Initialize an empty dictionary and loop through the iterator "it".
- Check if n is greater than 0 and current string is not present in the dictionary, then set default type as 1 otherwise increment by 1.
- At the end return the list of items.
- Finally initialize the iterator and display the histogram by calling the typeHistogram.

Answer:
2^11
Explanation:
Physical Memory Size = 32 KB = 32 x 2^10 B
Virtual Address space = 216 B
Page size is always equal to frame size.
Page size = 16 B. Therefore, Frame size = 16 B
If there is a restriction, the number of bits is calculated like this:
number of page entries = 2^[log2(physical memory size) - log2(n bit machine)]
where
physical memory size = 32KB which is the restriction
n bit machine = frame size = 16
Hence, we have page entries = 2^[log2(32*2^10) - log2(16)] = 2ˆ[15 - 4 ] = 2ˆ11
