In MATLAB, there is a very useful function called 'reshape', which can reshape a matrix into a new one with different size but keep its original data.
You're given a matrix represented by a two-dimensional array, and twopositiveintegersrandcrepresenting therownumber andcolumnnumber of the wanted reshaped matrix, respectively.
The reshaped matrix need to be filled with all the elements of the original matrix in the samerow-traversingorder as they were.
If the 'reshape' operation with given parameters is possible and legal, output the new reshaped matrix; Otherwise, output the original matrix.
Input:nums =[[1,2],[3,4]]r = 1, c = 4Output:[[1,2,3,4]]Explanation:Therow-traversingof nums is [1,2,3,4]. The new reshaped matrix is a 1 * 4 matrix, fill it row by row by using the previous list.
Input:nums =[[1,2],[3,4]]r = 2, c = 4Output:[[1,2],[3,4]]Explanation:There is no way to reshape a 2 * 2 matrix to a 2 * 4 matrix. So output the original matrix.
The height and width of the given matrix is in range [1, 100].
The given r and c are all positive.
