Binary Search Algorithm Tracing

Here is the code for a non$-$recursive binary search of an array of ints:

public static int binarySearch$($int

int mid $=0$;

int low $=0\frac{\text{;}}{\frac{?}{?}}$ initialize to index at the beginning of the array

int high $=$ numbersSize $-1\frac{\text{;}}{\frac{?}{?}}$ initialize to index at the end of the array

while $($high $$ low$)\{$

mid high $+$ low
