Question
Use the recursive method binarySearch given below and an array a given as an image below, to complete the following question:
Suppose I make a method call: binarySearch(a, 51, 0, a.length - 1);. How many recursive binarySearch calls are made before returning?
Note: Don't include the first method call: binarySearch(a, 51, 0, a.length - 1); as part of your count.
Method:
public int binarySearch(int[] n, int key, int lo, int hi) {
if (lohi) {
return -1;
}
int mid= lo + (hi - lo) / 2;
if (keya[mid]) {
}
else if (key > a[mid]) {
}
}
else {
}
a (array):
return binarySearch(a, key, lo, mid - 1);
6
0
return binarySearch(a, key, mid + 1, hi);
return mid;
