Code used for Submit/Run operation

class Solution:
    def minOperations(self, nums: List[int]) -> int:
        n = len(nums)
        if n < 3:
            return -1

        ops = 0
        for i in range(n - 2):
            if nums[i] == 0:
                ops += 1
                for j in range(i, i + 3):
                    nums[j] ^= 1  # Flip the element

        if nums[n - 2] == 0 or nums[n - 1] == 0:
            return -1

        return ops

Expected behavior

class Solution:
def minOperations(self, nums: List[int]) -> int:
n = len(nums)
if n < 3:
return -1

    ops = 0
    for i in range(n - 2):
        if nums[i] == 0:
            ops += 1
            for j in range(i, i + 3):
                nums[j] ^= 1  # Flip the element

    if nums[n - 2] == 0 or nums[n - 1] == 0:
        return -1

    return ops
