To calculate the sum of Fibonacci numbers less than 100 in Blockly, which loop block would you use?

- Dãy Fibonacci bắt đầu từ 0, 1, 1, 2, 3, 5, 8, ..., nhưng chỉ các số nhỏ hơn 100 (0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89) được cộng vào tổng.

-  Tổng sẽ là: 0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 + 55 + 89 = 232.
