title: Sort in-place; without dynamically allocate new memory (using LinkedList)
body: <p>What is in-Place Sorting?</p>
  
  <p>I wanted to sort a linked list (sort must be in-place), and not allowed to use any new memory.</p>
  
  <p>How can we sort without using a temporary Node?</p>
  
  <p>Thanks,
  Isa</p>
