$1+3+5+\ldots+2017+2019-2 -4-6-\ldots-2016-2018$  $=1+(3-2)+(5-4)+\cdots +(2017-2016)+(2019-2018)$  $=1+1+1+\cdots +1+1$  $=1010$ 
What is the value of $1+3+5+\ldots+2017+2019-2 -4-6-\ldots-2016-2018$? (Adapted from $2018$ AMC 8 Problem, Question \#5) 
1) $$1007$$ 
2) $$1008$$ 
3) $$1009$$ 
4) $$1010$$ 
5) $$1011$$
