CodeForces 567C Geometric Progression - He also has a favorite integer k and a sequence a, consisting of n integers. a Its values rarely coincide for different inputs. It may be possible that there are infinitely many such progressions, in which case you won't even try to look for them! A2OJ Category: sortings - GitHub Pages Description: I'm terribly tired, so I made a crooked algorithm to construct an arithmetic progression. (ans+k) db, s stdnumeded = st + (num - 1)ed. b Maybe some kind of "hashing" will work: suppose we have a function from list of numbers to number such that: Then we can find min, max and length of the range given in query, that is, there is only one candidate for arithmetic sequence that our range can form, and we just compare their hashes. d lcm(da,db)=dc dcdb Codeforces Otherwise, print the number of finite arithmetic progressions which could be your lost progression $$$A$$$ modulo $$$10^9+7$$$. c da, l c 3 Problem - 978D - Codeforces The first line contains a single integer $$$n$$$ $$$(1 \le n \le 100\,000)$$$ the number of elements in $$$b$$$.

An arithmetic progression or arithmetic sequence is a sequence of integers such that the subtraction of element with its previous element ($$$x_i - x_{i - 1}$$$, where $$$i \ge 2$$$) is constant such difference is called a common difference of the sequence. stcstb + kdb Two arithmetic progressions are considered different if they differ in their first term, common difference or number of terms. c d a b a
