The way u print a matrix in spiral order, same logic u can use to form the
matrix from given input PROVIDED the order of matrix is given ...
and this can be done in O(m x n) complexity...

Both problems are essentially the same. You need to traverse the matrix in a
spiral order and has a pretty straight forward solution.

Looking at the original question at the beginning at this thread, ... I
really can't rephrase it to the one you just mentioned. All it needs is the
"matrix", ... who cares about printing it out.

Hi,
I think the question is not to FORM A MATRIX, but to PRINT the elements
in the form of spiral matrix, where the problem of SEQUENTIAL OUTPUT
comes...

Should be O(n) where n is the number of inputs.
Keep a displacement info for 4 directions ... strictly in this order: right,
down, left, up. Starting from the top left corner/cell and current
direction is right ... continue putting the numbers one by one and advance
the cell based on your current
