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.
