pacman squares

least squares, usually used in our known mathematical model, but do not know the model parameters of the case, through the measured data to calculate the mathematical model, for example, in the problem, the mathematical model is the linear equation y=ax+b, but do not know the linear equation of a and B. Originally, we only need two groups (Xi,yi), we can solve A and B, but because of the measured data there are errors, so it is easy to think of a wa

Hdu_1569 There was no idea at the beginning, and later I came to the others' solution report saying that we should construct a bipartite graph and convert it into a minimal cut. Later, I thought about it again. The general principle is as

The core of this question is the judgment of the retrieved numbers. There are basically two methods to judge the background. 1. converting to a string for determination is also a reference in the answer. (The idea is relatively simple. I will not

LeetCode -- Perfect SquaresDescriptionGiven 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
