Algorithm for finding a key by binary search technique, Data Structure & Algorithms

Assignment Help:

Q. Write down an algorithm for finding a key from a sorted list using the binary search technique or method.                                                                                                                      

Ans.

Binary Search Algorithm is written below

1.   if (low > high)

2.     return (-1)

3.    mid = (low +high)/2;

4    .if ( X = = a [mid])

5     return (mid);

6     if ( X < a [mid])

7    search for X in a (low) to [mid -1];

8    else

9     search for X in a [mid + 1] to a [high];
