how to calculate perfect square

As mentioned above, in addition to classification algorithms, the feature extraction algorithms for processing classification texts also have a huge impact on the final effect. Feature Extraction algorithms are classified into feature selection and

GivenNIntegers you cangenerate2n-1Non-empty Subsets from them. determine for howsets of these subsets the product of all the integers in that is a perfectsquare. for example for the set {4, 6, 10, 15} There are3 such subsets. {4}, {6, 10, 15} and {4,

Given a positive integer n, find the least number of perfect square numbers (for example, 1, 4, 9, 16, ... ) which sum to n. For example, given n = 12 , return 3 because 12 = 4 + 4 + 4 ; given n = 13 , return 2 because 13 = 4 + 9
