CF893F Subtree Minimum Query 输入输出格式 输入格式: The first line contains two integers \(n\) and \(r\) ( \(1<=r<=n<=100000\) ) - the number of vertices in the tree and the index of the root, respectively. The second line contains n integers \(a_{1},a_{2}…
Range Minimum Query (RMQ) Write a program which manipulates a sequence A = {a0,a1,...,an−1} with the following operations: find(s,t): report the mimimum element in as,as+1,...,at. update(i,x): change ai to x. Note that the initial values of ai (i=0,1…
