/*
  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
