Answer #1

To run binary search array should be sorted.
Given array is: 30, 4, 28, 15, 7, 6
Sorted array of given array is: 4, 6, 7, 15, 28, 30 
low Index high Index mid = low+(high-low)/2 array[mid] Match (array[mid]=15)
0 5 2 7 No
3 5 4 28 No
3 3 3 15 Yes

So, Match found at index 3 in sorted array.
