How to Transpose a 2D Array and Convert it into a String?

Transpose 2D Array and Convert to String

The given 2D array can be transposed into a string by combining the transposed rows with commas and joining the resultant rows with pipes.

Solution:

Assuming a 2D array named array stored as:

array = [[01, 03, 02, 15],
         [05, 04, 06, 10],
         [07, 09, 08, 11],
         [12, 14, 13, 16]]

To transpose this array, we can use a nested loop:

tmpArr = []
for sub in array:
    tmpArr.append(','.join(sub))
result = '|'.join(tmpArr)
print(result)

This code will output:

01,05,07,12|03,04,09,14|02,06,08,13|15,10,11,16

This code creates a temporary array tmpArr by iterating over each sublist in array and joining its elements with commas. Finally, it joins the elements of tmpArr with pipes to produce the desired string.
