Python leetcode67: binary sum

subject ：

Here are two binary strings , Returns the sum of them （ In binary ）.

Input is   Non empty   String and contains only numbers  1  and  0.

for example ：

Input : a = "11", b = "1" Output : "100"

solution ：

Consider the simplest approach ： First the  a  and  b  Convert to decimal , Sum and convert to binary numbers .

class Solution:
def addBinary(self, a: str, b: str) -> str:
return bin(int(a, 2) + int(b, 2))[2:]
#int(x, base=10),base The default is 10 Base number
# bin() Returns an integer int Or long integers longint The binary representation of .
a = "11"
b = "1"
S = Solution()
result = S.addBinary(a,b)
print(result)
