双指针法)classSolution{public:intremoveElement(vector<int>& nums,intval){intres =0;// 存储去重后数组元素个数for(inti =0; i < nums.size(); ++i)// 快指针i遍历数组if(nums[i] != val)// 若快指针指向元素不是目标元素nums[res++] = nums[i];// 则慢指针res+1,且慢指针指向快指针当前元素...
Note that the input array is passed in byreference, which means modification to the input array will be known to the caller as well. Internally you can think of this: 代码语言:txt AI代码解释 // nums 是以“引用”方式传递的。也就是说,不对实参作任何拷贝 int len = removeElement(nums, val...
