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).

\n\n

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

\n\n

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

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "00110"\nOutput: 1\nExplanation: We flip the last digit to get 00111.\n
\n\n

Example 2:

\n\n
\nInput: s = "010110"\nOutput: 2\nExplanation: We flip to get 011111, or alternatively 000111.\n
\n\n

Example 3:

\n\n
\nInput: s = "00011000"\nOutput: 2\nExplanation: We flip to get 00000000.\n
