If some sides have different squares, you can just spell a larger square, which is called the perfect square.Historically, it took a long time to find a few perfect squares. For example: 22 squares with a length below2 3 4 6 7 8 12 13 14 15 16 17 18

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

Title Description: give a positive integer, do not use built-in functions, such as sqrt (), to determine whether this number is a number of squares. Idea: Direct use of dichotomy, seemingly nothing to say. The code is as follows:1 classsolution
