Using sliding window technique to find subarray with sum equal to k.

• Initialize two pointers at the start of the array.

• Move the right pointer to expand the window until the sum is greater than or equal to k.

• Move the left pointer to shrink the window if the sum exceeds k.

• Repeat until the end of the array is reached.

• Example: Input array [1, 4, 20, 3, 10, 5], k=33. Output: [20, 3, 10].
