Given an array of integers, every element appears twice except for one. Find that single one.
因为只有一个数是一个,其余都为2个,故采用一直异或下去就可以求得结果
class Solution { public: int singleNumber(int A[], int n) { for(int i = 0; i < n; i++) { if(n == 1) { return A[0]; } if(i == 0) { i++; } A[0] ^= A[i]; } return A[0]; } };
