Is B, all about case analysis? Any easier way?
After some analysis, it comes up that there are actually only three significant cases:
1) Δ x or Δ y is equal to zero;
2) Δ x and Δ y have the same sign (both greater than 0 or both less than 0);
3) Δ x and Δ y have different signs.
Can't find upsolving again.
The letter-indexes of the problems in upsolving differs from letter-indexes in statements.
Given that, there will be qualification round of deadline24, will there be opencup next week?
