Given an array and a value, remove all instances of that value in place and return the new length.
The order of elements can be changed. It doesn‘t matter what you leave beyond the new length.
1 class Solution { 2 public: 3 int removeElement(vector<int>& nums, int val) { 4 int length = 0; 5 for(int i = 0; i < nums.size(); i++){ 6 if(nums[i] != val) 7 nums[length++] = nums[i]; 8 } 9 return length; 10 } 11 };
