Sliding Window with Counting

  1. Initialize a counter count to 0.
  2. Iterate through the array with index i from 0 to len(arr) - m.
  3. Compare the current element arr[i] with the element m positions ahead arr[i+m].
  4. If they are the same, increment count.
  5. If they are different, reset count to 0.
  6. If count reaches (k-1)*m, return true as we have found the pattern repeated k times.
  7. If the loop ends without returning true, return false as no such pattern exists.
