AOJ 740 summation, aoj740 summationLink: http://icpc.ahu.edu.cn/OJ/Problem.aspx? Id = 740 Description for positive integers n, k, we define such a function f, which satisfies the following rules:F (n, k = 1) =-1 + 2-3 + 4-5 + 6... nF (n, k = 2) =-1-2 + 3 + 4-5-6... nF (n, k = 3) =-1-2-3 + 4 + 5 + 6... nF (n, k = 4) =-1-2-3-4 + 5 + 6 + 7 + 8... nGiven n and k, your task is to calculate the value of f (n, k.
Question: there is an existing encoding. When the Shift key is down or up, it corresponds to two types of encoding, two of which correspond to the shift operation.
Returns the corresponding encoding value to the string.
Analysis: analog, String. Simple question: Mark shift for classification.
Note: If the data volume is small, scan and query the data directly.
