Board Coloring

  • square
  • color
  • x
  • lines
  • each

Problem Description
HH is painting a board of size 4 * N. You can assume the color of square (X, Y) on the board is Ax,y which is an integer between 0 and 255. For the beauty of the board, HH decide to paint the board following the rules :
1) Ax,y >= Ax,y-1.
2) For some given pairs of (X1, Y1) (X2, Y2), AX1,Y1 = AX2,Y2
Your task is to calculate how many ways there are to paint the board.

Input
There are multiple test cases, the first line of input contains a single integer denoting the number of test cases.
For each test case, the first line contains an integer N and M, denoting the length of the board and the number of additional rules. (1 <= N <= 15, 0 <= M <= 100)
For next M lines, each line contains four integers X1, Y1, X2, Y2 denoting one additional rule for the painting. (1 <= X1, X2 <= 4, 1 <= Y1, Y2 <= N)

Output
For each test cases, you are to output the number of ways of painting. Because there may be too many ways, you are only to output the last five digits. See sample output for further details.

Sample Input
3
1 0
1 3
1 1 2 1
1 1 3 1
4 1 3 1
2 6
1 1 2 1
1 1 3 1
1 1 4 1
1 2 2 2
1 2 3 2
1 2 4 2

Sample Output
Case 1: 67296
Case 2: 00256
Case 3: 32896
