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 pos = 0; 5 for(int i = 0;i<nums.size();i++){ 6 if(nums[i]!=val){ 7 nums[pos]=nums[i]; 8 pos++; 9 } 10 } 11 return pos; 12 } 13 };
