Remove Nth Node From End

intermediatelayer B9 · Linked lists5 tests

Remove the nth node counting from the end of the list and return the head of the result.

  • n = 1 means the last node
  • n is always valid: 1 <= n <= length
  • Removing the only node leaves an empty list — return null
  • Try to do it in a single pass
