Question
If a is an array that contains the values from 1 to 100 in order. How may comparisons
are done to search for 50 using the binary search algorithm ?
hint: 50 is at index 50 in the array.
Binary search code:
int [] a = new int[100];
for (int i
a[i]
}
int key
7
0; i < a.length; i++) {
i+1;
8
9.
10
50;
boolean found =
11
%3D
12
false;
int low
0;
a.length
while(low <= high && !found){
int mid = (1low + high) / 2;
a[mid])
13
14
int high
1;

17
if(key
==
18
found
true;
else if(key > a[mid])
low = mid + 1;
