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];
