Combat rules answer
Their 1/1 deathtouch double striker blocked my 5/5 — does mine die before it deals damage?
Answer
Yes. The engine puts the 5/5 in its owner's graveyard and leaves the 1/1 blocker on the battlefield with no damage marked.
Why
Deathtouch means damage from the 1/1 can be lethal to the 5/5.
The resolved board has the 5/5 in the graveyard and the blocker still in play with 0 damage marked.
