how to find soundex number

There is only one number in a set of data that appears once, and all the other numbers are paired, please find this number.(using bit operations)Use the XOR operation directly.The code is as follows:#include This article is from the "Materfer" blog, make sure to keep this source http://10741357.blog.51cto.com/10731357/1708445Only one

Given an array of integers, the remaining elements appear two times, except for an element. Please find out this element that appears only once.Note:Your algorithm should be a linear time-of-day complexity. Can you implement it without extra space?See: https://leetcode.com/problems/single-number/description/Class Solution {public: int singlenumber (vectorThe 136 single

We know that looking for a maximum number in a data set with a capacity of N, no matter what comparison algorithm is used, it should be at least n-1 times, even if it is sorted by a competition, it will be n-1 times, otherwise, you cannot guarantee the maximum number. So what is the minimum number of comparisons between the maximum

5.7 An array A contains all the integers from 0 to n, except for one number which is missing. In this problem, we cannot access an entire integer in a with a single operation. The elements of represented in binary, and the only operation we can use to access them is "fetch the jth bit of a[i ], "which takes constant time. Write code to find the missing integer. Can do it in 0 (n) time?This problem gives us
