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. ...
There are a large number of numbers residing on multiple nodes (storage + commodity compute), you have one main compute server where you can perform your computing, find all distinct pairs which equal to a sum of "target" and the count of those pairs, now you can't load all the numbers...
