I think "parse" should be replaced by "editorial" everywhere, is it a mistranslation?

E was good. I was doing n(n-1)(n-2)..../2*3*4..mod 1e9+7 but that was wrong solution. Btw, what's the intuition behind the formula for i+j-2 for finding the nth row?

Edit: nvm I wasn't dividing properly for the above formula to work. Thanks for the contest learned inverse mod division.
