Output
Finding Addition_Result of each row:
Addition_Result of the row 0 = 21
Addition_Result of the row 1 = 57
Addition_Result of the row 2 = 93
Addition_Result of the row 3 = 129
Addition_Result of the row 4 = 165
Addition_Result of the row 5 = 201
Finding Addition_Result of each column:
Addition_Result of the column 0 = 96
Addition_Result of the column 1 = 102
Addition_Result of the column 2 = 108
Addition_Result of the column 3 = 114
Addition_Result of the column 4 = 120
Addition_Result of the column 5 = 126
