Example 1:

Input: text = "ABABDABACDABABCABAB", pattern = "ABABCABAB"

Output: [10]

Explanation: The pattern 'ABABCABAB' is found at index 10 of the text.

Example 2:

Input: text = "GEEKSFORGEEKS", pattern = "GEEK"

Output: [0, 8]

Explanation: The pattern 'GEEK' is found at indices 0 and 8 of the text.

Example 3:

Input: text = "TEST", pattern = ""

Output: [0, 1, 2, 3]

Explanation: Since the pattern is empty, it's considered to be found at every index of the text.
