hdu 3809 Decrypt coordinate （水。。）

点击打开链接PS:题目意思:让你求解方程：x1=x-sqrt(y);y1=y-sqrt(x);已知x1,y1,要求x与y,精确到小数点后6位。解题思路；迭代法，式子是这样推的：x=x1+sqrt(y);y=y1+sqrt(x);然后一开始把y=y1,x=x1赋值上去迭代，因为x>x1,y>y1;所以这样迭代上去，值会累加。可是为什么累加后值不会超过真实的x与y呢。。。因为x=x1+sqrt(y1+

HDU 3809 Decrypt coordinate（坐标解密）

题目大意：x1=x–sqrt(y)y1=y–sqrt(x)题目给出多个x1，y1.求出x，y。如果有多种可能的话，就输出x较小的那一对x，y。思路：一开始我还以为是纯几何。囧。。后来只好偷看答案了，迭代！神了，因为有2个方程，2个未知数，但是因为不是齐次方程，所以解起来麻烦。怎么迭代呢？因为x=x1+sqrt(y)       y=y1+sqrt(x)，先把x1，y1存下来之后，把x1，y1当成x

加密(encryption)算法：将普通信息（明文,plaintext）转换成难以理解的资料（密文,ciphertext）的过程；解密(decryption)算法则是其相反的过程：由密文转换回明文；加解密包含了这两种算法
