4: Write a Python program to check if a given string is a palindrome or not.
Hint: Input: ‘racecar’ Output: ‘racecar’ is a palindrome

5: Write a Python program to find the largest product of any two numbers in a given list of integers.
Hint: Input: [1, 5, 2, 6, 7, 0, 10, 11] Output: 110

6: Write a Python program to find the intersection of two lists.
Hint: Input: [1, 2, 3, 4], [3, 4, 5, 6] Output: [3, 4]

7: Write a Python program to find the largest prime factor of a given number.
Hint: Input: 13195 Output: 29

## Solutions

1: Solution Question 1

```number = int(input("Enter a number: "))
if number % 2 == 0:
print(number, "is even")
else:
print(number, "is odd")
```

2: Solution Question 2

```year = int(input("Enter a year: "))
if year % 4 == 0 and (year % 100 != 0 or year % 400 == 0):
print(year, "is a leap year")
else:
print(year, "is not a leap year")
```

3: Solution Question 3

```a,b,c = map(int, input().split())

largest_number = a

if b > a:
largest_number = b
if c > largest_number:
largest_number = c

print(largest_number)```

4: Solution Question 4

```string = input("Enter a string: ")
if string == string[::-1]:
print(string, "is a palindrome")
else:
print(string, "is not a palindrome")
```

5: Solution Question 5

```list1 = [1, 5, 2, 6, 7, 0, 10, 11]

list1.sort(reverse=True)
total = 1

for num in range(2):
total *= list1[num]

print(total)```

6: Solution Question 6

```list1 = [1,2,3,4]
list2 = [3,4,5,6]

output_list = []

for element in list1:
if element in list2:
output_list.append(element)

print(output_list)```

7: Solution Question 7

```def largest_prime_factor(n):
i = 2
while i <= n:
if n % i == 0:
n = n / i
largest_factor = i
else:
i += 1
return largest_factor

print(largest_prime_factor(13195))
```

Solving the above Python decision-making problems can significantly improve your problem-solving skills and logical thinking ability. These problems cover a wide range of difficulty levels, which will help you gain a deep understanding of how decision-making constructs work in Python and how they can be used to solve complex problems. These skills are valuable for anyone looking to develop their programming skills, especially for those interested in data science, machine learning, and artificial intelligence. Additionally, practicing with these problems can help you prepare for coding interviews and improve your chances of landing a job in the tech industry.
