Description
You are to implement a program asking the user to input two integers m and n corresponding to an mxn matrix, followed by all entries of that matrix as shown in the input. Your program should do nothing more than outputting the matrix. Be careful not to output any extra whitespaces at the end and always put a '\n' at the end of the output. You may assume the maximum colums and rows of the input matrix is 10, and you do not need to check whether the input is correct or not.
Input

12 8
3 17
9 8
Output
12 8

Description
The user is expected to input an array of integers (possibly negative) and your program determines whether there exists a subarray (which is a nonempty subset of the array consisting of consecutive elements) whose elements sum to zero. Output "yes" or "no" followed by '\n'. The input format is the same as Lab 6-2. You can assume the maximum length of the input array is 20. In the given example, the input is {4, 2, -3, 1, 6}, which contains a subarray {2, -3, 1} whose elements sum to 0.
Input
5
4 2 -3 1 6
Output
yes
