isn't the recursive binary search really just more code? Becuase it just states another way to do the loop, just without a while..

Algorithms: Searching

  • Searching is looking for a particular value in a collection
  • If the collection is not sorted, every value must potentially be searched
  • If the collection is sorted, it is possible to search much more efficiently
  • Sequential Search examines every value; must be used if collection is not sorted
  • Binary Search is much faster than Sequential Search for large collections of data but can only be used if the data is sorted
  • Binary Search can be implemented either iteratively or recursively
