Project Euler 106:special subset sums:meta-testing special subset and: meta-test

Special subset Sums:meta-testingLet S (A) represent the sum of elements in set A of size n. We shall call it a special sum set if for any of the non-empty disjoint subsets, B and C, the following properties is true: S (B) ≠s (C); That's,

C # determines that a set is a subset of another set,

C # determines that a set is a subset of another set, There are two sets:   String [] bigArr = new string [] {"a", "B", "c "};String [] smallArr = new string [] {"a", "B "};   Now we need to determine whether smallArr is a subset of bigArr. If

C # determines that a collection is a subset of another collection

There are two of these collections:string[] Bigarr = new string[] {"A", "B", "C"};string[] Smallarr = new string[] {"A", "B"};Now you need to determine if Smallarr is a subset of Bigarr. As long as holding the Bigarray and Smallarr comparison, the

A simple method of determining whether a set is a subset of another set in C # _c# tutorial

To see this title, we first thought of looping through one of the arrays, to determine whether each element in the array appears in another array, so that the array is not a subset of another array, but this is too complicated, there is no simple

C language implementation to find the problem of string subset

The problem is that when the Apriori algorithm is implemented, the association rules of each frequent set are required, and the true subset of each frequent set needs to be obtained in the most frequent concentration. Then in the implementation of
