If we store the signal row wise and compute the L point DFT at each column, the resulting array must be multiplied by which of the following factors?

If we store the signal row wise and compute the L point DFT at each column, the resulting array must be multiplied by which of the following factors? Correct Answer WNpm

According to the second algorithm of divide and conquer approach, if the input signal is stored in row wise, then we calculate the L point DFT of each column and we multiply the resulting array by the factor WNpm.
