[LeetCode]#2413. Smallest Even Multiple

Environment: Python 3.8

Key technique: int, float

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.

Analysis:

1. If (int n/2)=(float n/2), return n.
2. Else return n*2.

Solution

class Solution:
    def smallestEvenMultiple(self, n):
        p=int(n/2)
        if(p==float(n)/2):
            return n
        else:
            return n*2
