The Question:single numberGiven an array of integers, every element appears twice except for one. Find the single one.Note:Your algorithm should has a linear runtime complexity. Could you implement it without using extra memory?My Analysis:This problem could is solved in the very tricky ways. At here, I only use"XOR" method, and I would discuss the methond of using "digits counting"later. The key Idea:the property of Xor.x^ x = 0x^ Y ^ x =Y (the order
