At first, I thought it was OK to use bit arithmetic with or a few loops, counting to find out ...Or a fixed point of view, I assume that there is a length of n, the total number of permutations f (n), how to count him? Consider from the back forward,

Algorithm to solve this problem:The first step: an array to quickly find the two numbers that satisfy the condition.The second step: first for A[0],j Point after the first, K points to the last, if A[J] + A[k] -a[0], K –; so only O (n) Time

Given sorted integer Arrays nums1 and nums2, merge nums2 into nums1 as one sorted Array.Note:Assume that nums1 have enough space (size that's greater or equal to m + n) to hold add Itional elements from nums2. The number of elements initialized in
