| [DESAFIO / LANGUAGE WAR] Implemente um programa na sua linguagem favorita onde o usuário digita um número x, e o programa calcula o somatório dos x primeiros números pares da sequência fibonacci, e imprime a soma dos algarismos desse número. | |
| Por exemplo, quando x = 5, a resposta é 17, pois: | |
| 1. A sequência fibonacci é 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233,... | |
| 2. Os 5 primeiros números pares são 0, 2, 8 e 34, 144. | |
| 3. O somatório disso é 188. | |
| 4. Somando os algarismos, 1+8+8 = 17 |
