Question 1

Write a Python program that accepts a positive integer and finds:

the number of digits,
the sum of its digits,
the largest digit,
the smallest digit.

Example

Input: 58327

Number of digits = 5
Sum of digits = 25
Largest digit = 8
Smallest digit = 2

n = int(input("Enter a positive integer: "))

temp = n
count = 0
digit_sum = 0
largest = 0
smallest = 9

while temp > 0:
    digit = temp % 10
    count += 1
    digit_sum += digit

    if digit > largest:
        largest = digit

    if digit < smallest:
        smallest = digit

    temp //= 10

print("Number of digits =", count)
print("Sum of digits =", digit_sum)
print("Largest digit =", largest)
print("Smallest digit =", smallest)

Question 2

Write a Python program that accepts a sentence and counts the number of:

uppercase letters,
lowercase letters,
digits,
spaces,
other characters.

Example

Input: Python Lab 2026!

Uppercase letters = 2
Lowercase letters = 7
Digits = 4
Spaces = 2
Other characters = 1

text = input("Enter a sentence: ")

upper = 0
lower = 0
digits = 0
spaces = 0
others = 0

for ch in text:
    if ch.isupper():
        upper += 1
    elif ch.islower():
        lower += 1
    elif ch.isdigit():
        digits += 1
    elif ch.isspace():
        spaces += 1
    else:
        others += 1

print("Uppercase letters =", upper)
print("Lowercase letters =", lower)
print("Digits =", digits)
print("Spaces =", spaces)
print("Other characters =", others)

Question 3

Given a list of integers, find the second largest distinct number.

Example

Input:
[10, 40, 20, 40, 30]

Output:
Second largest = 30

numbers = [10, 40, 20, 40, 30]

largest = None
second_largest = None

for num in numbers:
    if largest is None or num > largest:
        if num != largest:
            second_largest = largest
            largest = num
    elif num != largest and (second_largest is None or num > second_largest):
        second_largest = num

print("Second largest =", second_largest)

Question 4

Write a Python program that removes duplicate elements from a list without changing the order of the remaining elements.

Example

Input:
[4, 2, 4, 1, 2, 5, 1]

Output:
[4, 2, 1, 5]

numbers = [4, 2, 4, 1, 2, 5, 1]

result = []

for num in numbers:
    if num not in result:
        result.append(num)

print(result)
