为下面的代码生成测试用例：public int searchint nums int target int l = 0 r = numslength - 1; whilel = r int mid = l + r 2; ifnumsmid target l = mid + 1;

测试用例：

1. nums = [1, 3, 5, 7, 9], target = 3，期望输出结果为 1
2. nums = [1, 3, 5, 7, 9], target = 6，期望输出结果为 -1
3. nums = [1, 3, 5, 7, 9], target = 9，期望输出结果为 4
4. nums = [1], target = 1，期望输出结果为 0
5. nums = [1], target = 2，期望输出结果为 -1
6. nums = [], target = 1，期望输出结果为 -1（空数组）
