    import re

def solve(matrix, n, m):
    string = ""
    # Here I use zip which transposes the matrix; that means it converts rows into columns
    # You can also use numpy
    # Using nested loops is not ideal in Python, so zip is used to avoid that
    matrix_T = list(zip(*matrix))
  
    for i in matrix_T:
        string += "".join(list(i))
    
    clear = re.sub(r'(?<=[a-zA-Z0-9_])[!@#$%&" "]+(?=[a-zA-Z0-9_])', ' ', string)
    
    print(clear)
