This is a super simple problem.The description is simple,the solution is simple.If you believe so,just read it on.Or if you don't,just pretend that you can't see this one.
We say an element is inside a matrix if it has four neighboring elements in the matrix (Those at the corner have two and on the edge have three).An element inside a matrix is called "nice" when its value equals the sum of its four neighbors.A matrix is called "k-nice" if and only if k of the elements inside the matrix are "nice".
Now given the size of the matrix and the value of k,you are to output any one of the "k-nice" matrix of the given size.It is guaranteed that there is always a solution to every test case.
