It’s a little complicated :thinking:

So the code sets a budget: a maximum number of comparisons it’s allowed to make before it must stop and say “this is too hard.”

How the budget is calculated?

  • It takes the combined size of the two texts and multiplies by 200. Bigger texts get a bigger budget.
  • But there’s a hard ceiling of 2 million comparisons—no matter how big the texts are, it will never try more than that.

What happens when the budget runs out?

  • The code raises its hand and says “I give up”—it throws an error (DiffLimitExceeded) rather than letting the server grind away for seconds or minutes :grimacing:
