Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0? Find all unique triplets in the array which gives the sum ...
題目描述 給定一個包含 n 個整數的數組nums,判斷nums中是否存在三個元素 a,b,c ,使得a b c 找出所有滿足條件且不重復的三元組。 注意:答案中不可以包含重復的三元組。 解題思路 首先對數組從小到大排序,從一個數開始遍歷,若該數大於 ,后面的數不可能與其相加和為 ,所以跳過 否則該數可能是滿足要求的第一個數,這樣可以轉化為求后面數組中兩數之和為該數的相反數的問題。定義兩個指針一前 ...
