Swap Nodes in Pairs (Medium)links：Title: https://oj.leetcode.com/problems/swap-nodes-in-pairs/Code (GitHub): Https://github.com/illuz/leetcodeTest Instructions：Swap each pair of nodes in a list (not just the value).Analysis：Direct simulation can be done.It would be convenient to open a front node to do it.

Given a linked list, swap every, adjacent nodes and return its head.For example,Given 1->2->3->4 , you should return the list as 2->1->4->3 .Your algorithm should use only constant space. Modify the values in the list, only nodes itself can be changed.Give a list of 22 exchanges.My train of thought is two pairs of two pairs to see, but divides into three kinds of situations, this pair and the following sit

Ipairs and pairs are all functions that traverse Tbale in Lua, but the two are different.1.pairs iterates through all the key-vale in the table and ipairs increments the corresponding table[i] value from 1 and 1 based on the value of the key.Pairs can traverse all the keys in the table and can return nil in addition to the iterator itself and the traversal table itself; However, Ipairs cannot return nil, on

http://www.practice.geeksforgeeks.org/problem-page.php?pid=387Find sum of different corresponding bits for all pairsWe define F (X, Y) as number of different corresponding bits in binary representation of X and Y. For example, F (2, 7) = 2, since binary representation of 2 and 7 is 010 and 111, respectively. The first and the third bit differ, so f (2, 7) = 2.You is given an array of N integers, A1, A2,..., A. Find sum of f (Ai, Aj) for all pairs (I,
