You may assume that each input would have exactly one solution, and you may not use thesameelement twice. Example: Given nums = [2, 7, 11, 15], target = 9, Because nums[0] + nums[1] = 2 + 7 = 9,return [0, 1]. Python code 1. Brute Force classSolution:deftwoSum(self, nu...
publicclassSolution{publicintgetSum(int a,int b){if(b==0)returna;int sum,up;sum=a^b;up=(a&b)<<1;returngetSum(sum,up);}} 代码很简单,递归调用,在每次调用中都先检查进位的计算是不是为0了,也就是是不是没有进位了,如果没有了说明异或运算就是最终结果了,如果还有进位就继续算下去,算异或和...
