Consider the following C program that attempts to locate an element x in an array Y[] using binary search. The program is erroneous.

```
1. f(int Y[10], int x) {
2. int i, j, k;
3. i = 0; j = 9;
4. do {
5. k = (i + j) /2;
6. if( Y[k] < x) i = k; else j = k;
7. } while(Y[k] != x && i < j);
8. if(Y[k] == x) printf ("x is in the array ") ;
9. else printf (" x is not in the array ") ;
10. }
```

The correction needed in the program to make it work properly is 2
