This is the code that does the same:
>
>
public static int search(int a[], int l, int u, int x) {
while (l <= u) {
int m = (l + u) / 2;
if (x == a[m]) {
return m;
} else if (a[l] <= a[m]) {
if (x > a[m]) {
l = m+1;
} else if (x >=a [l]) {
u = m-1;
} else {
l = m+1;
}
}
else if (x < a[m]) u = m-1;
else if (x <= a[u]) l = m+1;
else u = m - 1;
}
return -1;
}
public static int search(int a[], int x) {
return search(a, 0, a.length - 1, x);
}
