TopicGive a positive integer n to find several complete squares (e.g. 1, 4, 9, ...) Make their sum equal to N. You need to have the fewest number of squares.Sample ExampleGive n = 12 , return 3 because 12 = 4 + 4 + 4 .Give n = 13 , return 2 because 1

The so-called perfect checkerboard coverage is like this. On the 8-by-8 chess board, cover it with a 1-by-2 rectangle. Shows the checkerboard: If all the grids on the board are covered, and there is no leakage or repeated coverage, then such

We know that any element in an array can be accessed within an O (1) time by direct addressing via an array (directly addressing). Therefore, if the storage space allows, you can provide an array, for each possible keyword to maintain a location,

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

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
