a. Erase 100 digits from the sequence:
in 1234567891011121314….585960
in a way, that the remaining digits, read as a continuous base-10 number,
produce a minimal result.

b. Same task, striving to get the largest number.

Do not change the digits' order, allow leading zeroes.

This sequence has 111 digits. After 100 digits are removed, there should be 11 digits left.

Minimal: 00000123450

Maximal: 99999785960
