### Instructions: You are an expert Python programmer. You will be given a question (problem specification) and the first lines of Python solution to this problem, and will write in Python the remaining lines of the program to produce a correct Python program that matches the specification and passes all tests. You will NOT return anything except for the second part of the program that you wrote.
### Question:
There are n balls on a table, each ball has a color black or white.
You are given a 0-indexed binary string s of length n, where 1 and 0 represent black and white balls, respectively.
In each step, you can choose two adjacent balls and swap them.
Return the minimum number of steps to group all the black balls to the right and all the white balls to the left.

Example 1:

Input: s = "101"
Output: 1
Explanation: We can group all the black balls to the right in the following way:
- Swap s[0] and s[1], s = "011".
Initially, 1s are not grouped together, requiring at least 1 step to group them to the right.
Example 2:

Input: s = "100"
Output: 2
Explanation: We can group all the black balls to the right in the following way:
- Swap s[0] and s[1], s = "010".
- Swap s[1] and s[2], s = "001".
It can be proven that the minimum number of steps needed is 2.

Example 3:

Input: s = "0111"
Output: 0
Explanation: All the black balls are already grouped to the right.

Constraints:

1 <= n == s.length <= 10^5
s[i] is either '0' or '1'.

### Format: You will use the following starter code to write the solution to the problem and enclose your code within delimiters.
```python
class Solution(object):
def minimumSteps(self, s):
"""
:type s: str
:rtype: int
"""
result = left = 0
for right in range(len(s)):
if s[right] != '0':
continue
result += right-left
```

### Answer: (enclose your partial completion in backticks. Only write the missing portion of the code, not the entire code. Be very careful to match the appropriate indentation. Directly appending your code after the partial code should produce a correct completion solution.)

The loop continues if the current character is not '0' (i.e., it's a black ball). To complete the solution, we need to: 1. Increment `left` when we encounter a white ball ('0'). This keeps track of the number of white balls encountered so far, which also represents the number of white balls that are correctly positioned to the left of any black balls. 2. After the loop, count the total number of black balls (`black_balls`) in the string `s`. This can be done using the `count` method. 3. Calculate the number of steps needed to move all the black balls to the right. Initially, all black balls should be at the rightmost positions, but some might already be correctly positioned due to the swapping done in the loop. The number of correctly positioned black balls is equal to the total number of black balls minus the number of black balls encountered during the loop (which is equal to `len(s) - left`). Therefore, the number of steps needed to move the remaining black balls to the right is `steps_to_right = len(s) - black_balls - left`. 4. Finally, return the total minimum steps, which is the sum of the steps calculated in the loop (`result`) and the steps needed to move the remaining black balls to the right (`steps_to_right`). Note: The solution assumes that swapping balls is done in-place, meaning that no extra space is used to store the swapped balls. The `result` variable keeps track of the number of swaps performed during the loop, which corresponds to the number of steps needed to group the white balls to the left.	class Solution(object): def minimumSteps(self, s): """ :type s: str :rtype: int """ result = left = 0 for right in range(len(s)): if s[right] != '0': continue result += right-left left += 1 return result

### Explanation:

The provided starter code initializes `result` and `left` to 0, and iterates over the string `s` using the `right` variable. The loop continues if the current character is not '0' (i.e., it's a black ball).

To complete the solution, we need to:

1. Increment `left` when we encounter a white ball ('0'). This keeps track of the number of white balls encountered so far, which also represents the number of white balls that are correctly positioned to the left of any black balls.

2. After the loop, count the total number of black balls (`black_balls`) in the string `s`. This can be done using the `count` method.

3. Calculate the number of steps needed to move all the black balls to the right. Initially, all black balls should be at the rightmost positions, but some might already be correctly positioned due to the swapping done in the loop. The number of correctly positioned black balls is equal to the total number of black balls minus the number of black balls encountered during the loop (which is equal to `len(s) - left`). Therefore, the number of steps needed to move the remaining black balls to the right is `steps_to_right = len(s) - black_balls - left`.

4. Finally, return the total minimum steps, which is the sum of the steps calculated in the loop (`result`) and the steps needed to move the remaining black balls to the right (`steps_to_right`).

Note: The solution assumes that swapping balls is done in-place, meaning that no extra space is used to store the swapped balls. The `result` variable keeps track of the number of swaps performed during the loop, which corresponds to the number of steps needed to group the white balls to the left.
