input: def compute_triangle_area(a, b, c):
      '''
      Given the lengths of three sides of a triangle, this function returns the area
      of the triangle rounded to two decimal places if the triangle is valid.
      Otherwise, it returns -1. A valid triangle's sides satisfy the condition
      where the sum of any two sides is greater than the third side.
      Example:
      compute_triangle_area(3, 4, 5) == 6.00
      compute_triangle_area(1, 2, 10) == -1
      '''
output:     # Check if the given sides form a valid triangle
      if a + b <= c or a + c <= b or b + c <= a:
          return -1
      
      # Calculate the semi-perimeter
      s = (a + b + c) / 2
      
      # Calculate the area using Heron's formula
      area = (s * (s - a) * (s - b) * (s - c)) ** 0.5
      
      # Round the area to two decimal places and return
      return round(area, 2)
