input: Write a function to compute the sum of square numbers in a given range, including the start and end numbers. The function should return the sum of the squares for all numbers within the specified range. If the range is empty, the function should return 0.
  
  def sumOfSquares(start, end):
      sum = 0
      for i in range(start, end+1):
          sum += i * i
      return sum
  
  assert sumOfSquares(10, 20) == 673
  assert sumOfSquares(0, 0) == 0
  assert sumOfSquares(5, 5) == 25
  assert sumOfSquares(1, 3) == 14
  assert sumOfSquares(15, 17) == 901
output: def sumOfSquares(start, end):
      sum = 0
      for i in range(start, end+1):
          sum += i * i
      return sum
