Intuition

the intuition to this problem was it would be easy. bizz buzz problem is one of the most common problem to test student can use conditional statement. I tried to solve this, but then, I had to make a function that converts integer into string. I don’t wanna do such thing, so I just changed into python.

Approach

easy approach. just add correct string to the list and return it. to get the correct, string use conditional statements.

Solution

class Solution:
    def fizzBuzz(self, n: int) -> List[str]:
        ans = []
        for i in range(1,n+1):
            if(i%15 == 0):
                ans.append("FizzBuzz")
            elif(i % 3 == 0):
                ans.append("Fizz")
            elif(i%5 == 0):
                ans.append("Buzz")
            else:
                ans.append(str(i))
        return ans

Complexity

• Time: $O(n)$

• Space: $O(n)$

Thoughts

I need real questinos.
