Which of the two snippets is correct?
Snippet-1:
```
n = 5
zero = '0' # len(zero) == 1
one = '1' # len(one) == 1
for i in range(n):
if i == 0 or i == n - 1:
print(zero * n)
else:
print(zero + one * (n - 2) + zero)
```
Snippet-2:
```
n = 5
zero = '0' # len(zero) == 1
one = '1' # len(one) == 1
for i in range(n):
for j in range(n):
if j == 0 or j == n - 1:
print(one, end='') # end argument is an empty string
else:
print(zero, end='') # end argument is an empty string
print()
```
Useful information - Input:
```
print('1', end='') # end argument is an empty string
print('2', end='') # end argument is an empty string
print()
print('3' * 5)

Q10
If `n` is a positive integer, then what will be the value of `count` at the end of execution of the code given below?
```
n = int(input())
count = 0
for x in range(1, n + 1):
for y in range(x + 1, n + 1):
count = count + 1
```
Single correct
Q11
Select all snippets of code that print the following sequence of `n` lines, where `n` is a positive integer that is already defined. The th line in the output corresponds to the first Fibonacci numbers, for . Assume that and are the first two Fibonacci numbers. There should be a single space after every number, including after the last number in any given line.
Sample output for `n = 7`:
```
0
0 1
0 1 1
0 1 1 2
0 1 1 2 3
0 1 1 2 3 5
0 1 1 2 3 5 8
```
Multiple correct
Q12
If `n` is a positive integer, what is the value of `count` at the end of execution of the code given below?
```
n = int(input())
count = 0
for x in range(1, n + 1):
for y in range(x + 1, n + 1):
count = count + 1
```
Single correct
Q13
The following code always accepts a positive even integer as input. What is the output produced by the code if the input is `1999999978`?
Hint: `999999989` is a prime number.
```
n = int(input())
f = n - 2
while (f >= 0) and (n % f != 0):
f = f - 2
print(f)
```
