因为这道题目没有规定我们不能改动 array,所以可以把array 里的 num 和在 nums[ num - 1 ] 做一对一的映射,每次遇到一个num, 把对应位置上的 num 改成 -num 标记。如果遇到一个重复项,那么肯定已经有同样的数字来标记过了。 Java Solution: Runtime beats 85.92% 完成日期:09/19/2017 关键词:Array 关...
这道题给了我们一个数组,数组中的数字可能出现一次或两次,让我们找出所有出现两次的数字,由于之前做过一道类似的题目Find the Duplicate Number,所以不是完全无从下手。这类问题的一个重要条件就是1 ≤ a[i] ≤ n (n = size of array),不然很难在O(1)空间和O(n)时间内完成。首先来看一种正负替换的方法...
