< Prev

How can a recursive method be modified to ensure it does not exceed the array bounds while traversing the array?

Suppose you are traversing an array using recursion. It is important to ensure that the method does not attempt to access an index beyond the array boundaries.
A

By decrementing the index on each recursive call regardless of its current value.

B

By including a condition that checks if the current index is greater than or equal to the array’s length.

C

By removing the base case altogether.

D

By using a static counter that ignores the actual array length.
