Numbers
I'm making problems about numbers, here's a list of them so far:
(I will slowly release editorials)
Notes
tfw your top problems are either scuffed or math related
update: still kinda scuffed, but getting better hopefully
note to self: sometimes c++ tles not because ur algorithm is too slow, but because ur array bounds aren't correct (this happened way too many times) usually just add some extra cells to ur array and it will work
update: I now always add extra cells to my arrays :)
other common errors (trivial yet deadly):
- index off by 1
- swapped rows and columns of a grid
- bad io (especially if you use an unsigned scan macro on negative integers D:)
- wrong data type
- misreading the problem statement (or not reading it at all)
- stupidity
