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'.
