To make it the least, you should make the digit in the first place as small as possible. Thus the $$2$$, $$3$$, $4$ and $$5$$ should be taken out. 
Take out $$4$$ digits from $101112131415$ to make the rest of the digits into a new $8-$digit number without changing the order of digits. The least possible value of the new number is~\uline{~~~~~~~~~~}~. 

1. $$10111111$$ 
2. $$10111110$$ 
3. $$10111100$$ 
4. $$10111011$$ 
5. $$10111112$$
