You are given following:- - an array A consisting of N positive integers - Q queries of the form L,R,M consider all subsequences of subarray from L to R of size M. Determine the sum of Bitwise OR of all these subsequences. Bitwise OR of an empty subsequence is 0. If there is no ...
Consider N boxes numbered 1 to N. Each box can house any number of chocolates. And initially all the boxes are empty. There are two types of queries that can be posed by the throwers. a. 0 l r -> Add chocolates to the boxes between the index l and r (inclusive) such that l'th...
由于随着右端点的增加圆肯定不断变大,所以右端点可以分成三段:[l,mid][l,mid]对应的圆完全包含[mid+1,r][mid+1,r]对应的圆,不存在包含关系和[l,mid][l,mid]对应的圆完全被[mid+1,r][mid+1,r]对应的圆包含,用 two pointers 维护三段分界点,左右两段显然可以O(1)O(1)求得,中间那段相当于要你维...
