Consider the routine below checks whether the input myArray contains three elements, a, b, and c such that a + b = c. Determine the run-time complexity of the routine using Big-O notation.

def check_for_sum_triplet(myArray):
  for element_a in myArray:
    for element_b in myArray:
      for element_c in myArray:
        if element_a + element_b == element_c:
          return TRUE

  return FALSE


The algorithm as written above has a run-time complexity of
