Remove Element

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 public class Solution {
 2     public int removeElement(int[] A, int elem) {
 3         // Note: The Solution object is instantiated only once and is reused by each test case.
 4         int start = 0;
 5         for(int i = 0; i < A.length; i ++){
 6             if(A[i] != elem){
 7                 A[start ++] = A[i];
 8             }
 9         }
10         return start;
11     }
12 }
