Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. Observe the given code.

private static int[] u={2,7,9,11,21,26,35,44};
public static int binaryS(int key)
{

int first=0;
int last=u. length-1;
while(first<=last)
{
int middle=(first+last/2);
if (u[middle]==key)
return middle;
else if(u[middle] first=middle+1;
else
last=middle-1;
}
return -1;
}

What will be stored in x after executing the following statement?

int x= binaryS(2);

The output will be
.
