Problem:
 Score : 200 points    Problem Statement There are N pieces of source code. The characteristics of the i -th code is represented by M integers A_{i1}, A_{i2}, ..., A_{iM} .  Additionally, you are given integers B_1, B_2, ..., B_M and C .  The i -th code correctly solves this problem if and only if A_{i1} B_1 + A_{i2} B_2 + ... + A_{iM} B_M + C > 0 .  Among the N codes, find the number of codes that correctly solve this problem.      Constraints  All values in input are integers.  1 \leq N, M \leq 20  -100 \leq A_{ij} \leq 100  -100 \leq B_i \leq 100  -100 \leq C \leq 100         Input Input is given from Standard Input in the following format:  N  M  C  B_1  B_2  ...  B_M  A_{11}  A_{12}  ...  A_{1M}  A_{21}  A_{22}  ...  A_{2M}  \vdots  A_{N1}  A_{N2}  ...  A_{NM}       Output Print the number of codes among the given N codes that correctly solve this problem.        Sample Input 1 2 3 -10
1 2 3
3 2 1
1 2 2      Sample Output 1 1  Only the second code correctly solves this problem, as follows:   Since 3 \times 1 + 2 \times 2 + 1 \times 3 + (-10) = 0 \leq 0 , the first code does not solve this problem.  1 \times 1 + 2 \times 2 + 2 \times 3 + (-10) = 1 > 0 , the second code solves this problem.        Sample Input 2 5 2 -4
-2 5
100 41
100 40
-3 0
-6 -2
18 -13      Sample Output 2 2       Sample Input 3 3 3 0
100 -100 0
0 100 100
100 100 100
-100 100 100      Sample Output 3 0  All of them are Wrong Answer . Except yours.
