(Print)
"how many ways..."
lifting the exponent
"find f(0)" or "f(1)"
trivial by modular arithmetic
hockey stick
Algebra or Geo problem is secretly a Combo problem
incorrect problem
"Alice and Bob play a game"
ugly exact form
roots of unity
off by one because edge case
draw at least 3 imaginary lines
euler totient function
am gm hm qm
calculus bait
random trig when its totally unnecessary
answer less than 10
one line AOPS solution
off by factor of two because sillies
"coord bashable"
problem difficulty out of order
complex numbers is actually geo problem
cauchy schwarz
maximize/minimize algebraic expression
"triangle ABC"
log base variable
burnside's lemma not strictly needed
average/ev problem
new random symbol in problem statement
cards/dice/chess
(fat expression)^2 >= 0
vieta's
bash to win
probability is geometry
at least two circles
3D tangent sphere
jumping on coordinate plane
copy pasted problem
"find largest integer satisfying..."
self-similar expression
trivial by semi-obscure identity
spoiler: it telescopes
