Web给定数组 nums = [1,1,2], 函数应该返回新的长度 2, 并且原数组 nums 的前两个元素被修改为 1, 2。 你不需要考虑数组中超出新长度后面的元素。 示例 2: 给定 nums = [0,0,1,1,1,2,2,3,3,4], 函数应该返回新的长度 5, 并且原数组 nums 的前五个元素被修改为 0, 1, 2, 3, 4。 你不需要考虑数组中超出新长度后面的元素。 Web中间位置的计算可以写作 mid = (low+high)/2 或者 mid = low+ (high-low)/2。 但前者的问题是low和high比较大时low+high可能会溢出，超出int表达的最大范围。 如果有对性能的极致要求，还可以把除2改为位运算，写作mid=low+ ( (high-low)>>1)，位运算的性能要比除法好很多。 错误写法：面试中看到很多人写作 mid = (high-low)/2，这种写法肯定是错误的， …
