Given an array of sizenn. How can we find sum of XOR sum of all subsets in better thanO(2n)O(2n)? For example considerarray=[1,4,5]array=[1,4,5] Answer = 1 + 4 + 5 + 1^4 + 1^5 + 4^5 + 1^4^5Answer = 1 + 4 + 5 + 1^4 + 1^5 + 4^5 + 1^4^5(here '^...

Ankit has a set of numbers and has recently studied set theory. He has created a power set of this set and is writing a program to compute sum of all elements of all the subsets in power set. Power set of a set S is defined as set of all possible subsets of S. Set S consist o...
Counting all rows in a table (no group by required) 计算表中的所有行(不需要按组) Counting the totals of subsets of data (requires a Group By section of the statement) 计算数据子集的总数(需要语句的“分组依据”部分) For reference, here is the current data for all the rows in our example...

All subarrays : [1], [1, 2], [1, 2, 3], [2], [2, 3], [3] here first element 'arr[0]' appears 3 times second element 'arr[1]' appears 4 times third element 'arr[2]' appears 3 times Every element arr[i] appears in two types of subsets: ...
A basic problem raised by Kneser was to describe all the finite subsets A, B of an abelian group G such that | A+B | ≤ | A | + | B | 1. Let G be an abelian group. The description of the pairsA , BG such that | A+B | = | A | + | B | 1 < |G | was ...

By extracting and summing cells from different areas of a spreadsheet, users can gain insight into different subsets of data, potentially uncovering patterns, trends, or outliers that might have gone unnoticed otherwise. This is easy, right? Yes. Summing random cells shows improvement in ...
