    664 - Strange Printer\.

    Hard

    There is a strange printer with the following two special properties:

    • The printer can only print a sequence of the same character each time.

    • At each turn, the printer can print new characters starting from and ending at any place and will cover the original existing characters.

    Given a string s, return the minimum number of turns the printer needed to print it.

    Example 1:

    Input: s = "aaabbb"

    Output: 2

    Explanation: Print "aaa" first and then print "bbb".

    Example 2:

    Input: s = "aba"

    Output: 2

    Explanation: Print "aaa" first and then print "b" from the second place of the string, which will cover the existing character 'a'.

    Constraints:

    • 1 <= s.length <= 100

    • s consists of lowercase English letters.
