1. How I sloved
I declared ‘output’. If ‘n’ is even, ‘a’ is appended to ‘output’. And ‘b’ is appended to ‘output’ for ‘n-1’ times.
2. Code
class Solution:
def generateTheString(self, n: int) -> str:
output = ''
if n%2==0:
output += 'a'
else:
output += 'b'
for _ in range(1,n):
output += 'b'
return output
3. Result
Runtime : 28 ms(78.92%), Memory usage : 13.8 MB(52.75%)
(Runtime can be different by a system even if it is a same code.)
