- * 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 eding
- * at any place and will cover the origin existing characters given a string
- * 's', return the minimum number of turns the printer needed to print it.
