CF509D Restoring Numbers
题目描述
给你一个n*m的矩阵v。
v[i][j]=(a[i]+b[j])%k;
求a,b数组及其模数k。
输入格式
第一行两个整数n,m。
接下来n行,每行m个数。
输出格式
如果a,b,k存在输出“YES”,并依次输出模数k和数组a,b;否则输出“NO”。
说明/提示
By  we denote the remainder of integer division of $ b $ by $ c $ .
It is guaranteed that if there exists some set of numbers $ k,a_{1},...,a_{n},b_{1},...,b_{m} $ , that you could use to make matrix $ w $ , then there also exists a set of numbers that meets the limits $ 1
