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.

复制代码
public class Solution {
    public int removeElement(int[] A, int elem) {
        int n = A.length;
        for (int i = 0; i < n; i++) {
             if (A[i] == elem) {
                 A[i] = A[n - 1];
                 n--;
                 i--;
            }
        }
        return n;
    }
}
复制代码
