    926 - Flip String to Monotone Increasing.

    Medium

    A binary string is monotone increasing if it consists of some number of 0’s (possibly none), followed by some number of 1’s (also possibly none).

    You are given a binary string s. You can flip s[i] changing it from 0 to 1 or from 1 to 0.

    Return the minimum number of flips to make s monotone increasing.

    Example 1:

    Input: s = “00110”

    Output: 1

    Explanation: We flip the last digit to get 00111.

    Example 2:

    Input: s = “010110”

    Output: 2

    Explanation: We flip to get 011111, or alternatively 000111.

    Example 3:

    Input: s = “00011000”

    Output: 2

    Explanation: We flip to get 00000000.

    Constraints:

    • 1 <= s.length <= 105
    • s[i] is either '0' or '1'.
