# 2413. Smallest Even Multiple

# Given a positive integer n, return the smallest positive integer that is a multiple of both 2 and n.

# Example 1:
# Input: n = 5
# Output: 10
# Explanation: The smallest multiple of both 5 and 2 is 10.

# Example 2:
# Input: n = 6
# Output: 6
# Explanation: The smallest multiple of both 6 and 2 is 6. Note that a number is a multiple of itself.

# Constraints:
# 1 <= n <= 150

class Solution:
    def smallestEvenMultiple(self, n: int) -> int:
        ''' Smallest Even Multiple '''
        return n if n % 2 == 0 else n * 2

print(Solution().smallestEvenMultiple(5))
# Output: 10
print(Solution().smallestEvenMultiple(6))
# Output: 6
