Mr Swan's Mega Component 2 Final Revision Quiz

Identify the search algorithm

• Spotlight search

• Binary search

• Denary search

• Next Item search

Identify the description of a linear search

• Put the elements in order, start at the first item, check each item in turn

• Put the elements in order, compare to the middle value, split the list in order and repeat

• Elements do not need to be in order, check each item in turn

• Elements do not need to be in order, compare to the middle value, split the list in order

  and repeat

Identify the description of a binary search

• Put the elements in order, start at the first item, check each item in turn

• Start with elements in order, compare to the middle value, split the list in half and repeat

• Elements do not need to be in order, check each item in turn

• Elements do not need to be in order, compare to the middle value, split the list in order

  and repeat
