Now there is a very long string s, in which all characters are ' 0' to ' 9' . It represents a very large number. You want to know how many different sequences of the string is a multiple of five. A sub-sequence is defined as a string to remove some elements any of the rest. Sequences required for the pilot may have 0, but can not be empty.
