This article mainly introduces the relevant knowledge of "how to solve the problem of C++ equal difference subsequence". The editor shows you the operation process through an actual case, and the operation method is simple, fast and practical. I hope this article "how to solve the problem of C++ subsequence" can help you solve the problem.
Problem description
Given an integer sequence, ask how many subsequences of the sequence are congruent.
That is to say, for the sequence containing N numbers, A _ (0), A _ (1), … , A (NMur1), how many groups are there (P (0), P (1), … , P (k)) satisfies 0
