题目描述

Dima took up the biology of bacteria, as a result of his experiments, he invented kk types of bacteria. Overall, there are nn bacteria at his laboratory right now, and the number of bacteria of type ii equals cic_{i} . For convenience, we will assume that all the bacteria are numbered from 11 to nn . The bacteria of type cic_{i} are numbered from to .

With the help of special equipment Dima can move energy from some bacteria into some other one. Of course, the use of such equipment is not free. Dima knows mm ways to move energy from some bacteria to another one. The way with number ii can be described with integers uiu_{i} , viv_{i} and xix_{i} mean that this way allows moving energy from bacteria with number uiu_{i} to bacteria with number viv_{i} or vice versa for xix_{i} dollars.

Dima's Chef (Inna) calls the type-distribution correct if there is a way (may be non-direct) to move energy from any bacteria of the particular type to any other bacteria of the same type (between any two bacteria of the same type) for zero cost.

As for correct type-distribution the cost of moving the energy depends only on the types of bacteria help Inna to determine is the type-distribution correct? If it is, print the matrix dd with size k×kk×k . Cell d[i][j]d[i][j] of this matrix must be equal to the minimal possible cost of energy-moving from bacteria with type ii to bacteria with type jj .

输入格式

The first line contains three integers n,m,kn,m,k (1<=n<=105; 0<=m<=105; 1<=k<=500)(1<=n<=10^{5}; 0<=m<=10^{5}; 1<=k<=500) . The next line contains kk integers c1,c2,...,ckc_{1},c_{2},...,c_{k} (1<=ci<=n)(1<=c_{i}<=n) . Each of the next mm lines contains three integers ui,vi,xiu_{i},v_{i},x_{i} (1<=ui,vi<=105; 0<=xi<=104)(1<=u_{i},v_{i}<=10^{5}; 0<=x_{i}<=10^{4}) . It is guaranteed that .

输出格式

If Dima's type-distribution is correct, print string «Yes», and then kk lines: in the ii -th line print integers d[i][1],d[i][2],...,d[i][k]d[i][1],d[i][2],...,d[i][k] (d[i][i]=0)(d[i][i]=0) . If there is no way to move energy from bacteria ii to bacteria jj appropriate d[i][j]d[i][j] must equal to -1. If the type-distribution isn't correct print «No».
