Let S={1,2,3,..., 100}. The number of non-empty subsets A of S such that the product of elements in A is even is
Given, set S={1,2,3, ..., 100}. Total number of non-empty subsets of 'S' =2^(100)-1 Now, numbers of non-empty subsets of 'S' in which only odd numbers [1,3,5, ..., 99} occurs =2^(50)-1 So, the required number of non-empty subsets of 'S' such tha
How many subsets of the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} contain the number 5? Let S = {1, 2, 3, 4}. The total number of unordered pairs of disjoint subsets of S is equal to (A) 25 (B) ...
A non-empty subset of nums is an array that can be obtained by deleting some (possibly none but not all) elements from nums . Two subsets are different if and only if the chosen indices to delete are different.Example 1:Input: nums = [3,4,4,5] Output: 3 Explanation: There are 3...

A hypergraph is a pair H=(V,E), where V is an n element set of vertices of H and E is a family of m non-empty subsets of V called edges or hyperedges. Let [k] denote the set of integers {1,…,k}. A k-coloring of hyperedges of H=(V,E) is a mapping c:E→[k] such...
The Stirling numbers of the second kind, or Stirling partition numbers, describe the number of ways a set with n elements can be partitioned into k disjoint, non-empty subsets. Common notations are S (n, k) and,-. The study is finalized with an extraordinary identity between the second ...
Critical hypergraphs with the minimal number of edges. The upper chromatic number χ ( H ) of a hypergraph H = ( X , E ) is the maximum number k for which there exists a partition of X into non-empty subsets X... Buršteĭn, M. I - 《Sakharth. Ssr Mecn:akad》 被引量: 21...
Let H = (V(H), E(H)) be a hypergraph, where V (H) is a set of vertices and E(H) is a set of non-empty subsets of V (H) called edges. If all edges of H have the same cardinality r, then H is an r-uniform hypergraph. A hypergraph H' = (V(H'), E(H')) is ...
