至此,终于把LeetCode Old OJ里的132题刷完了,小小的成就。 此题算法简单,就是O(n^2),采用和Two Sum类似的做法就是了。我的代码略有麻烦之处,主要是在函数里判断了一次abs的差值,外面又判断了一次,但总体不影响。 注意,先选定i,然后在i后面的元素做TwoSum,意思是当第一个元素是i时的结果,这样就不会重复。 也有不需要子函数的写法,更简洁:http://www.

暴力循环的时间复杂度是O(N^3),肯定是不可取的。我们要充分利用题目中的条件进行分析,如何才能相对高效的比较数组中指定个数元素的和 和target的大小呢?我们可以先对数组进行排序,如果是计算两个元素的和的话,我们会分别设置头和尾两个指针,向中间靠拢,那么三个的话,我们只需要先对第一个数进行循环取值下标i,剩下的两个指针分别指向i+1和数组的最后一个元素,这样的复杂度是 排序O(nlogn)+查
