Leaving the least (the most) (Posted on 2017-10-27) Difficulty: 2 of 5
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.
