Recently participated in a programming competition, there is a few question bank, this topic is one of them.Of course, if you want to exercise your programming level, you can go to Lintcode or other websites to brush the problem.I was so confident that it took me one hours to write it down, and I was ashamed.It was implemented using string, after all, it was programmed with C + +. Without thinking how to write, there is no use.Title Description: Given 2 positive integers a,

There are two arrays a and B whose sizes are n. By exchanging elements in a and B, sum (a)-sum (B) is minimized ., Sum-sum Today, when I browsed the web page, I found a link called Huawei interview questions (code written in 8 minutes). I'm not sure about the authenticity. It's just curious. Let's go and have a look. This may be a very old question, because I saw

Two arrays a [N], B [N], where each element value of A [N] is known, and B [I] is assigned a value, B [I] = a [0] * a [1] * a [2]… * A [N-1]/a [I] [Problem] 1. Division is not required. Two arrays a [N], B [N], where each element value of A [N] is known, and B [I] is assigne

Label:One: Create an index using B-tree B-tree To describe the B-tree, first define a data record as a two-tuple [key, Data],key is the key value of the record, for different data records, the key is not the same; data records for data other than key. Then B-tree is a data structure that meets the following criteria: 1
