/*
misread -> missed subtask
you thought u declared it huh?
not i but x
logical operator
wrong example/proof
thoroughly
wrong variables
thinking it wrong
bruh just try some test case
capitals ;-;
wrong data structure lol
count memory usement
corner case
oversized array
orders
statements
size initializer
while con
map -> array
wrong digits??
swapped variables??
check if theres any variabled
that got declared twice
find some pattern
name collision
constraints??!
mod !!
resets
