  wrong example/proof

  wrong variables
  thinking it wrong
  bruh just try some test case
  capitals ;-;
  wrong data structure lol
  count memory usement
  corner case
  oversized array

  map -> array
  wrong digits??
  swapped variables??
  check if theres any variabled
  that got declared twice
