In MATLAB, there is a handy function called
reshape which can reshape an
m x n matrix into a new one with a different size
r x c keeping its original data.
You are given an
m x n matrix
mat and two integers
c representing the row number and column number of the wanted reshaped matrix.
The reshaped matrix should be filled with all the elements of the original matrix in the same row-traversing order as they were.
reshape operation with given parameters is possible and legal, output the new reshaped matrix; Otherwise, output the original matrix.
Input: mat = [[1,2],[3,4]], r = 1, c = 4 Output: [[1,2,3,4]]
Input: mat = [[1,2],[3,4]], r = 2, c = 4 Output: [[1,2],[3,4]]
m == mat.length
n == mat[i].length
1 <= m, n <= 100
-1000 <= mat[i][j] <= 1000
1 <= r, c <= 300
