You can find the length (or size) of an ArrayList in Java using size() method. The size() method returns the number of elements present in the ArrayList. Syntax of size() method: public int size() Program to find length of ArrayList using size() In this
}for(intj = index; j<=nums.length; j++) { list.add(j); }returnlist; } 03 第二种解法 利用标记。因为1≤a[i]≤n,我们可以单独再新建一个数组,数组的长度是n+1,然后将nums中的元素作为索引,在新数组中对元素进行自加。然后判断新数组中,那些等于0的元素的索引就是nums中缺失的数。
