List findCommonNumber(int[] num1, int[] num2) {
    List result = new ArrayList();
    if(nums1.lenghth == 0 || nums2.length == 0)
        return result;
    int p1 = 0, p2 = 0;
    while(p1  num2[p2]) 
            p2++;
        else {
            result.add(num1[p1]);
            p1++;
            p2++;
