1414 - Find the Minimum Number of Fibonacci Numbers Whose Sum Is K\. Medium Given an integer `k`, _return the minimum number of Fibonacci numbers whose sum is equal to_ `k`. The same Fibonacci number can be used multiple times. The Fibonacci numbers are defined as: * F1 = 1 * F2 = 1 * Fn = Fn-1 + Fn-2 for `n > 2.` It is guaranteed that for the given constraints we can always find such Fibonacci numbers that sum up to `k`. **Example 1:** **Input:** k = 7 **Output:** 2 **Explanation:** The Fibonacci numbers are: 1, 1, 2, 3, 5, 8, 13, ... For k = 7 we can use 2 + 5 = 7. **Example 2:** **Input:** k = 10 **Output:** 2 **Explanation:** For k = 10 we can use 2 + 8 = 10. **Example 3:** **Input:** k = 19 **Output:** 3 **Explanation:** For k = 19 we can use 1 + 5 + 13 = 19. **Constraints:** * 1 <= k <= 109
