Below is a pseudo code representation of the Binary Search Algorithm.
What is its Big-O estimate, and why?
b. Show the Algorithm as a C++ function.
a.
procedure binary search (x: integer, a,, a2, .., an: increasing integers)
i com 1{i is left endpoint of search interval}
j n{j is right endpoint of search interval}
while i <j
m ((i+j)/2]
if x > am then i m + 1
else j= m
if x = a; then location i
%3D
else location 0
return location{location is the subscript i of the term a; equal to x, or o if x is not found}
