Super Binary String

The program must accept a string S containing only 0s and 1s as the input. The program must print Yes if the given string is a super binary string. Else the program must print No as the output. A super binary string must satisfy the following two conditions.
– The number of 1s must be equal to the number of 0s.
– In each prefix of the string, the number of 1s must be greater than or equal to the number of 0s in the prefix.

Hint:Optimize your logic to avoid Time Limit Exceeded Error.

Boundary Condition(s):
1 <= Length of S <= 10^6

Input Format:
The first line contains S.

Output Format:
The first line contains Yes or No.

Example Input/Output 1:
Input:
110010

Output:
Yes

Explanation:
Here S = “110010”.
The number of 1s in S = 3.
The number of 0s in S = 3.
In each prefix of S, the number of 1s is greater than or equal to the number of 0s.
1^st prefix: 1
2^nd prefix: 11
3^rd prefix: 110
4^th prefix: 1100
5^th prefix: 11001
6^th prefix: 110010
Hence Yes is printed as the output.

Example Input/Output 2:
Input:
1001

Output:
No

Example Input/Output 3:
Input:
11010

Output:
No

        break

    print("Yes" if one==zero else "No")
